AE 19.0 - Txnstore Migration 18.2 to19.0

In AE 19.0 Txnstore migration from 18.2
Whether we can run Migration Workbench tool multiple time, When one time failed in Validation steps?
Whether we need to clean and run the tool ?

Hi,

Pre-Req for migration is you need to keep back up of TxnStore data folder
In case your migration was interrupted as a best practice restore the old data folder and restart migration
