Hi There …
After migration from SQL Server to Percona MySQL 8.0 using AWS Database Migration Service & Schema Conversion
How to handle the ongoing changes happened at SQL Server …?
Is there anyway routing the traffic to Percona MySQL with NO downtime…?
Note : Application
As far as I know there is no tool that allows for live replication from SQLServer to MySQL. A quick google search revealed this page: https://www.techrepublic.com/blog/how-do-i/how-do-i-set-up-replication-between-microsoft-sql-server-2000-and-mysql/
You can route traffic to MySQL at any time. The only downtime is how long your applications take to move connections.
