I have a cliet who is upgrading the server from 12 to 13, it is currently has php accessing it. Windows 2010 server.
Would there be any gotchas with upgrading the server and leavin the workstations on 12?
The workstations do a lot of import/exporting of xls files from the workstations, which means I will need to change the scripts to xlsx, so the scripts will need to change before the workstations get upgraded. For now, I just want to know if there may be anything that could go wrong if I upgrade the server now, then after changing scripts, the workstations will get changed.
Any info if welcomed, thanks!
