Step 3: Set Up SAP Hana & Snowflake Account
The data migration process is finally set! Now it's time to put everything into action. The first step is to follow the instructions to create an account on Snowflake. After that, you'll need to connect your HANA database to Snowflake.
Make sure that all your deployment settings are updated so that they match those on your old system. Once everything is set up, you're ready to start data migration!
Step 4: Build a Data Extractor from SAP Hana
It's important to note that data migration is a time-consuming process, so make sure you have the right tools and expertise at your disposal. To make the process even easier, consider using a data extraction tool.
This will help you transfer all the necessary data from SAP HANA to Snowflake in a simple and efficient manner. The final step in data migration is to build a data extractor from SAP. This will allow you to easily access and analyze the data that has been migrated.
Step 5: Create Snowflake Tables
In this final step of the data migration process, we need to create a Snowflake tables migration script. Make sure to have a plan for how you'll structure the tables once they're in Snowflake, and be mindful of any dependencies between them. Also, be sure to use an ETL process that exports and imports the data in its most consumable form.
Step 6: Load into Snowflake
In step 6 - loading data into Snowflake. Before getting started, it's important to back up the SAP HANA database. Next, create a staging area in Snowflake for your data.
After you've exported your data, add it to your new schema in Snowflake. Make any necessary adjustments, and then export the data to Snowflake. Finally, load the data into the staging area and make sure it's working as expected.
If everything goes according to plan, you're ready to move on to the next stage - incorporating the data into your business applications!
Step 7: Do it on Schedule
There's no need to agonize over data migration anymore. With Snowflake, it's easy and straightforward. In this final step, make sure that everything goes according to plan.
Avoid any last-minute surprises and make sure you have all the necessary tools and resources ready before starting. As for the migration process, follow our detailed steps and create a Migration Schedule to make sure everything goes as smoothly as possible.
Make sure you have all the data you need before starting - data migration can be time-consuming, so make sure you're prepared!
Step 8: Optimizations
Next, identify and eliminate duplicate tables, optimize join queries, and more. By doing so, you'll minimize the data that needs to be moved and improve performance overall. In the end, one of the best practices for data migration from SAP HANA to Snowflake is to perform optimizations. This will help you optimize data warehouse tables for faster data retrieval and reduce the load on the data warehouse.

What are some common problems that occur when data is migrated from SAP HANA to Snowflake?
When data is migrated from SAP HANA to Snowflake, there are a few important things to keep in mind. One of the most common problems that occurs during data migration is data corruption. To reduce the risk of data corruption, it is important to follow established best practices for database development and deployment.
This means making sure that all data is entered correctly into both tables and fields, using the correct data type, and undergoing trial and error testing before proceeding with the migration.
Another problem that can occur during data migration is incompatibility between software modules. For instance, if a table in SAP HANA is linked to a table or view in Snowflake, there may be problems when the data is migrated.
These problems can include errors caused by differences in the formats of the two databases, as well as incompatibility issues between software modules. So, to minimize the risk of data migration problems, it's important to pay close attention to these three tips:
- Make sure all data is entered correctly into both tables and fields- use the correct data type
- Perform trial and error testing before starting the data migration and try different methods to see if any compatibility issues occur
- Check for any links between tables and views if any links exist
