I am trying to upgrade a PB 5.0 system to PB 12.6 (will eventually be migrated to 2017, once licence is organised). Yes there are still PB5.0 systems out there.
I am getting errors as "C0174: Type of actual parameter cannot be ancestor of formal reference parameter type.". I can see what the error is but just checking to see if I need to migrate in steps (i.e. maybe migrate to 6.5 or similar before migrating to 12.6).
Thanks in advance.
