Incremental migration from MSSQL to ORACLE

in Database Administration (MOSC) 2 commentsAnswered

Hi,

I am migrating 200 GB MS SQL (on-premise) to Oracle 19c (cloud) using SQL Developer migration tool. Upon testing, extracting data from the source takes around 12 hrs and about the same time for loading the data to Oracle. For data consistency, this means we need to have a downtime of almost 24 hours to migrate the data which is not viable for us.

Is there a way in which I can do an 'incremental' migration so that I can cut the downtime to a smaller time?

Thanks!
