Sage 100 2020 Upgrade with SQL Database from 2018 Provide X Database

Curious if anyone knows when we are moving our data from Sage 2018 ProvideX Database to Sage 2020 SQL Database for some reason unknown 3 customers didn't carry over. We use Mapadoc and one of them customers is using that. Any ideas on what would cause this or on how to resolve this. IF anyone has experienced similar.
