Perspective Playback Control from ignition exchange behaving inconsistently

Playback Controls fails in following scenarios:
-When i restore the Gateway backup in another machine
-When i change the OPC server path of the Tags
-When i change table name in the database.
To fix it earlier i used to restart the transaction group or the gateway. even that’s not not working now.
Is there any steps i need to follow while migrating to another system or anything i missed?
