I've been asked to upgrade a GroupOffice from 1.94 to the current version.
I understand that I need to upgrade to 2.18 first. I have installed this and pointed at the data, however it fails to recognise the current version of the data, and I have to enter the version. So I enter 1.94 and then it says
Setting max_executing_time to one hour.
Current version: 194
The version number 194 is invalid
I note it says 194 not 1.94 - not sure why. In any case, I can go no further.
Do I need an earlier version than 2.18? If so does anyone want to recommend a version and let me know where to find it - the sourceforge repository doesn't seem to go back much further.
Many thanks in advance.
