I am a former library employee, now library volunteer, who is helping a library systems that is using tikiwiki as their internal intranet.
They are using an old version of tikiwiki, somewhere in the version 4 range, and I would like to get them to the newest version.
Can anybody give me any tips/recommendation/docs on the best way to go about this? Should I upgrade by version, 4-5-6-7, can I go right from 4 to 7? Steps in between?
