I have done the first phrase of Percona XtraDB cluster 5.7.x to Percona XtraDB cluster 8.0.19 migration from one host to the other. it looks ok before handle over to developer to test.
but any pre migration check by any tools can help to check any unknown issue as the migration gap so that we know what has to take care before this kind of migration.
I just do not want to miss anything! right now table, data, mysql logic all migrated to the Percona XtraDB cluster 8.0.19
we have to let developer know before real migration
