									<p>ETL allows businesses to consolidate data from multiple databases and other sources into a single repository with the data that has been modified and used during the analysis of data. This unified data repository allows for simplified access to analysis and additional processing of the data. There are many advantages of using ETL tools for the migration of data. It reduces delivery time, reduces unnecessary expenses, makes the process easy to use, and also will be simple for data migrations. Data Integration, Data Warehousing, and Data Migration are the three common uses of ETL.</p>								</div>

<!-- FAQs: ETL Testing Stages in Snowflake -->
<section class="faq-section" aria-labelledby="faq-heading">
  <h2 id="faq-heading">Frequently Asked Questions: ETL Testing Stages in Snowflake</h2>

  <div class="faq-list">
    <details>
      <summary>1) What are the main stages of ETL testing in Snowflake?</summary>
      <p>
        ETL testing in Snowflake follows extraction, transformation, and loading — extracting data (often from
        Snowflake itself), transforming it to meet business requirements, and loading it to a target using
        components like DB Sink.
      </p>
    </details>

    <details>
      <summary>2) How is data extracted for ETL testing in DataOps Suite?</summary>
      <p>
        Data can be extracted from the same source or from multiple source locations — for example, customer
        data extracted directly from a Snowflake table as the starting point for the ETL testing process.
      </p>
    </details>

    <details>
      <summary>3) How is transformed data loaded in DataOps Suite&#8217;s ETL testing process?</summary>
      <p>
        Once transformation is complete, data is loaded to the target location using a DB Sink component, which
        represents the final loading step of the ETL process.
      </p>
    </details>

    <details>
      <summary>4) How are reports validated after ETL testing in Snowflake is complete?</summary>
      <p>
        Once the ETL process is done, the generated reports are checked and validated using BI Validator to
        confirm they reflect the transformed and loaded data accurately.
      </p>

									<p>This blog explains how Datagaps validates data movement between on-premises databases and Snowflake, and between Snowflake instances, using DataFlow. A real client case study covers migrating 400 SQL Server tables (500M+ rows each) to <span style="text-decoration: underline; color: #1967d2;"><a style="color: #1967d2; text-decoration: underline;" href="https://www.datagaps.com/cloud-data-test-automation/snowflake/" target="_blank" rel="noopener">Snowflake</a></span>, surfacing issues like numeric precision differences, null inconsistencies, and truncation. It also covers transitioning from ETL to ELT, BI Validator-driven regression testing, and AWS EMR cluster auto-scaling to over 30 nodes—achieving roughly a 50% reduction in test cycle time.</p>								</div>

									<p><strong>Key Takeaways</strong></p><ul><li>Bulk migration testing catches issues at scale — using the Data Migration Wizard, a client generated comparison tests for 400 SQL Server tables (500M+ rows each) in just a few hours, surfacing numeric precision, null value, and truncation issues.</li><li>DataFlow supports the ETL-to-ELT transition — as the client shifted their pipeline architecture toward Snowflake, DataFlow validated accuracy across iterations until source and target data were fully in sync.</li><li>BI Validator extends testing to the reporting layer — clients use it for regression, performance, and stress testing to compare BI dashboards and reports between the old warehouse and new Snowflake implementation.</li><li>AWS EMR auto-scaling improves testing efficiency — DataOps Suite&#8217;s cluster integration scaled EMR nodes up to 30+ during comparisons of 500M-record tables, then scaled down after, cutting testing costs while achieving an estimated 50% reduction in test cycle time.</li></ul>								</div>

									This article describes ways in which we can test the data movement between Snowflake and on-premises data and between instances of Snowflake itself. We will also provide some benchmarks for doing comparison testing for large volumes of data moved into Snowflake. Another benefit of the Datagaps approach is, as additional data is moved into the Snowflake structure from other sources, Datagaps provides the ability to monitor the quality of your data structures by continually providing an up to date scoring so that you can determine when data is becoming corrupted.								</div>

									<p>They started the initial migration by performing bulk loads from 400 SQL Server tables to Snowflake with minimal transformations. This was stage 0, where they could perform source and target data comparison for over 500 million rows of data per table. Making use of the Data Migration wizard, the client was able to generate comparison tests for 400 tables in just a few hours. Even though there were few changes at this stage, they still encountered errors that were surfaced by our<br />DataFlow product.</p>								</div>

									<p>Next, they began to perform incremental new data migrations where they continued to find similar issues that had to be corrected. As this continued, they wanted to transition from this incremental new data migration from SQL Server to loading the new data directly into Snowflake to reap the benefits stated earlier. To accomplish this, their initial ETL processes needed to be migrated to an ELT process aimed at Snowflake.</p>								</div>

After a short period of testing, they could cut over to the new system and deprecate the SQL server environment.

									Many of our clients take this one step further by testing their BI tools against the old warehouse and the new Snowflake implementation. They do regression, performance, and stress testing using our BI Validator tool to compare the old with the new. They can find differences in the look and feel in the output generation of the reports and dashboards. Differences are exposed between the report queries when compared to a database query.

									<h3 id="faq-heading">FAQs: Snowflake Data Migration Validation</h3>

<section class="faq-section" aria-labelledby="faq-heading">

    <div class="faq-list">

        <details>
            <summary>1) What kind of data validation is needed when migrating to Snowflake?</summary>
            <p>
                Snowflake migrations require validating data transferred from on-premises
                databases as well as comparisons between Snowflake environments. Validation helps
                identify issues such as numeric precision differences, null value mismatches, data
                truncation, and other inconsistencies introduced during migration.
            </p>
        </details>

        <details>
            <summary>2) How does the Data Migration Wizard help with large-scale migrations?</summary>
            <p>
                The Data Migration Wizard automatically generates comparison tests for large
                numbers of tables, significantly reducing manual effort. For example, it has been
                used to validate hundreds of SQL Server tables containing hundreds of millions of
                rows, enabling organizations to quickly identify migration discrepancies at scale.
            </p>
        </details>

        <details>
            <summary>3) How does BI Validator support Snowflake migrations beyond the database layer?</summary>
            <p>
                BI Validator extends migration validation to reports and dashboards by performing
                automated regression testing, performance testing, and stress testing. This helps
                ensure reporting outputs remain accurate and consistent after migrating from a
                legacy data warehouse to Snowflake.
            </p>
        </details>

        <details>
            <summary>4) How does AWS EMR cluster integration improve testing performance during migration?</summary>
            <p>
                DataOps Suite can automatically scale AWS EMR clusters to support resource-intensive
                comparisons of very large datasets and then scale them down when processing is
                complete. This approach improves performance, optimizes infrastructure costs, and
                helps reduce overall migration testing time.
            </p>

									<p>Migrating from a legacy data warehouse to Snowflake requires validation at each step. This guide outlines a four-step process using Datagaps DataFlow: comparing extracted data (row counts, encoding, completeness) between the legacy warehouse and AWS S3, validating transformations using Data Profile and Data Rules components, verifying data loaded into Snowflake against staging files, and end-to-end validation. It also covers using BI Validator to test report accuracy, layout, performance, and security after switching reports to Snowflake.</p>								</div>

									<p><strong>Key Takeaways</strong></p><p> </p><ul><li>Extraction validation confirms lossless data movement — comparing row counts, data encoding, completeness, and values between the legacy warehouse and AWS S3 landing zone ensures nothing was lost during extraction.</li><li>Transformation step requires data quality checks before load — Data Profile and Data Rules components help identify and curate data quality issues before syncing data to the staging zone, ahead of loading into Snowflake.</li><li>DataFlow supports single-test, end-to-end validation — a single DataFlow can validate data between the legacy warehouse and S3, as well as between the legacy warehouse and Snowflake, in one unified test.</li><li>Reports need separate validation after migration — BI Validator checks report data accuracy, layout, performance, security, and stress-tests reports under concurrent user loads to confirm they function correctly once switched to Snowflake.</li></ul>								</div>

									<p>Data is typically extracted into CSV or Parquet format and moved to a landing zone in AWS S3. Depending on the data volumes, AWS offers multiple options for moving the files to S3. Once the data has been moved to AWS S3, data validations need to be performed to ensure that all the data was properly extracted and migrated to AWS S3. Since there are not many transformations in this step, these tests are typically one-to-one comparisons of the data in the tables in the legacy data warehouse and the files in the AWS S3 landing zone.</p>								</div>

									<p>Migrating to Snowflake is never just a lift-and-shift — it&#8217;s a multi-stage process where errors introduced at extraction or transformation can silently propagate all the way through to the reports business users rely on every day. By validating data at each stage — comparing row counts and values as data moves from the legacy warehouse to S3, profiling and curating data during transformation, and reconciling loaded data against Snowflake — teams can catch discrepancies before they compound. And because reports rarely translate one-to-one across platforms, testing report accuracy, layout, performance, and security after the switch is just as critical as validating the underlying data. With tools like Datagaps DataFlow and BI Validator automating these checks at every step, organizations can move to Snowflake with confidence that their data — and the reports built on it — remain accurate and trustworthy from day one.</p>								</div>

									<h3 id="faq-heading">FAQs: Snowflake Data Migration Validation</h3>

<section class="faq-section" aria-labelledby="faq-heading">

    <div class="faq-list">

        <details>
            <summary>1) What are the main steps involved in validating a Snowflake data migration?</summary>
            <p>
                Snowflake migration validation typically includes four stages: validating data
                extraction from the legacy data warehouse to AWS S3, verifying data
                transformations and quality in the staging area, comparing staged data with data
                loaded into Snowflake, and validating BI reports after they are connected to the
                new Snowflake environment.
            </p>
        </details>

        <details>
            <summary>2) How is data extraction validated when migrating to Snowflake?</summary>
            <p>
                Extraction validation compares row counts, data completeness, encoding, and
                actual data values between the legacy source system and the files written to AWS
                S3. This ensures data is transferred accurately before any transformation or
                loading takes place.
            </p>
        </details>

        <details>
            <summary>3) Why is data profiling important before loading data into Snowflake?</summary>
            <p>
                Data profiling identifies quality issues such as missing values, invalid formats,
                and inconsistencies before data is loaded into Snowflake. Cleaning and validating
                data in the staging area helps ensure only accurate, high-quality data reaches the
                target warehouse.
            </p>
        </details>

        <details>
            <summary>4) What does report validation involve after migrating to Snowflake?</summary>
            <p>
                Post-migration report validation verifies that dashboards and reports produce the
                same results as before migration. It includes checking data accuracy, visual
                consistency, report performance, stress testing under concurrent usage, and
                confirming that security and user access permissions remain correctly configured.
            </p>
