Thread:Project:Support desk/Problems upgrading from an older version of Mediawiki

I am attempting to upgrade a wiki from mediawiki version 1.11.0 to the latest version. The site I am upgrading has its own specific skin and addition configurations. My issues arrive from the fact that the original wiki uses php5.2.14 and does not migrate to php5.3.8. I originally upgraded from 1.11.0 to 1.13 and then to 1.15.5 and was then able to move to php5.3.8. However, this broke something with the database since I could not log on. I had been able to get most of the custom images to work, but could not get any further then version 1.15.5. I really need to move to the latest version and get to php5.3.8. Is there a recommended procedure for such an upgrade.
