Hi!
Hope I can get some help with this from you gyus:
Since my payment module had compability issues with newer VM versions I had to stick to VM 2.0.1. But now, finally, the module has been updated and according to the changelog it will work with VM2.0.21b.
My queston is if it´s ok to go from 2.0.1 to 2.0.21b in one step. Or do I need to update in smaller steps? I also wonder which Joomla version I should go with. Right now I´m running 2.5.9.
Thank´s for any input on this!
As of today everyone needs to go to 2.0.22c - http://virtuemart.net/news/list-all-news/446-important-security-release-vm-team-at-joomladay-germany
But first update your insecure Joomla version to the current 2.5.14 (don't you subscribe to security/update info?)
To update VM all that way in one go is too much. I'd suggest somthing like up to 2.0.8e first, then 2.0.12f and then to 2.0.22c
If you use template overrides then they will need updating, too.
Thank´s for your reply, Jenkin. I´ll try it out as you suggest. And yes I know, sloppy of me not to update Joomla. It´s taken care of now :-)
