UC external tables to managed tables

[frosti_pro]

Dear community,

I would like to know if there are any procedure and/or recommendation to safely and efficiently migrate UC external tables to managed tables (in a production context with high volume of data)?

Thank you for your support!

Hi there @frosti_pro , 
So you can have a look at this blog https://www.databricks.com/blog/migrating-tables-hive-metastore-unity-catalog-metastore , helped me a lot when we were doing migrations for a client

There's a tool from databricks called databricks-ucx which is used for migration from hive metastore to UC. 
You can also have a look at it for migrating from external to managed tables will get an idea or step required
https://databrickslabs.github.io/ucx/docs/process/#migrate-hive-metastore-data-objects

Your usecase is different you want to migrated from UC external to managed , so not all the things will be same but you can get an idea on how to plan the procedure for production

Thank you @ashraf1395 for your reply! I am surprised to see there is no official procedure for my usecase. Thank you again.
