[Vtigercrm-developers] Custom modules and migrating to vt7.5.0

Wed Jul 26 18:21:12 GMT 2023

Alan, my understanding was that when you execute, for example, the
migration script from 6.4 to 6.5, the vtiger.zip gets first unzipped with
the files that are changed/new in vt 6.5. So you effectively have vtiger
6.5 code. THEN the database migration script gets executed. And my
assumption was that such script would rely on being executed in the vtiger
6.5 code context. Using your method, all those database migration scripts
would be run against your final target vtiger version (say 7.5). But from
what you say, it seems that there is no such dependency  and that all
database migration scripts can be run against vtiger's last target version
(say again 7.5). Are we on the same page?
