v25 installed in wrong folder

SUGGESTED

On Monday a colleague reported not being able to back up Sage50 Accounts. It looks as though they updated to from v24 to v25 and the installation path is in /Accounts/2014 not /Accounts/2019 where I would have expected it to be.

I'm assuming that I can just move some files from /2014 to /2019 and edit the company file but what do I need to move and are there any other steps/precautions I need to take?

Any help gratefully received.
