Hi Juraj,
Some background, we recently upgraded a clients site from version 7 all the way to version 9 and applied the hotfix 11 to solve a scheduled task memory issue.
- Upgraded form 7 to 8 => ran site
- Upgraded form 8.0 to 8.1 => ran site
- Upgraded form 8.1 to 8.2 => ran site
- Upgraded form 8.1 to 8.2 => ran site
- Upgraded form 8.2 to 9.0(.1) => ran site
- Upgraded form 9.1 to 9.11 hotfix => ran site
The upgrade was successful (We did need to merge in some custom code), and the event logs show some images that are not found, http://devnet.kentico.com/questions/cms-image-issue-after-upgrade, but nothing else that I can see.
I believe that I have resigned the macros, but a link to directions would be helpful to ensure that this was done correctly.
Thanks,
Chris
