Hi, Barbara. I rarely ""re-migrate"" when doing an upgrade, so I usually move the PL Logs manually.
ASSUMING that the Paperless folders have not moved, I rename the 3 PL_logs (for JournalsRegisters, Reports, PEreport) in MAS_SYSTEM folder) in the new system (V2016). Then, I'll take a copy of the 3 PLlogs from the OLD system (V2013). Paste them into the new system. Your logs are now updated. I do involve one of our programmers if the folders have moved.
Logs for customer and vendor forms are in the data files themselves and will move automatically with your cut and paste of MAS_XXX.
