Thank you! Not sure I fully follow what is explained on that link, though.
That table next to “Tip” with the column “Can Upgrade to 10.2.1?” on your link tells me that it is not always the same for different versions. 9.1.0 can go to 10.2.1, and so can 9.1.8, but 9.0.8 cannot while 9.0.9 can.
Not being tightly in the loop with oc development, I am not sure what the last point release is for my current installation (where does 10.0 end?). It would be nice to have a list of releases I need to “jump” through in order to get to the latest version.
Meanwhile I found that the updating mechanism in the admin interface also has some built-in logic how to upgrade: For my 10.0.10.4 version, it suggests to upgrade to 10.1.1 and then to 10.3.0, which will skip 10.2. Doesn’t this contradict the guidelines on the link you posted?
Overall, the upgrade path is still rather confusing to me - and since I need to backup over 1 GB of data with each upgrade, I cannot do it with every point release. So I am bound to be in the same position again in the near future…
