Hi Everyone,
We has just migrated from 12.2 to 14.0 MII, we did not got any issue in BLS or any Queries. The only issue we faced was the tag Query. So, after migrating from 12.2 to 14.0 we need to re load the Tag query and save it after migration to 14.0 otherwise it will not work as expected.
Am sharing as many of us may be working for Migration of MII 12.2 to 14.0, this may be useful.
