Hello,
I have two servers running ownCloud. One of them is running version 8.2.11, the other one is running the latest version, 10.0.10.
Both are used in a work environment with a little over 100 users.
I need to migrate the caldav calendars from the 8.2.11 ownCloud server to the 10.0.10 ownCloud server.
I can think of three ways of doing this:
- upgrade the 8.2.11 ownCloud server (or a copy of it) step-by-step to the latest version. However, I don’t feel strongly about this option, as I’m simply looking for a way to migrate the calendars. I don’t want to migrate the entire server setup.
- Copy the MySQL database entries. However, it is my understanding that the MySQL database structure for ownCloud changes between major versions, and the calendar entries have a different format in 8.2.11 and 10.0.10.
- manually log-in on every user account, download/export the calendars, and then import them again on the new server. However, this option won’t work well. Even if I had the time and patience to do it, I cannot nilly-willy reset people’s LDAP passwords to log-in on their accounts. It’s not an elegant solution. But if there was an option to do this in an automated fashion, without having to actually log-in on people’s accounts, then I think this would be the way to go.
My question is: Is there a good, effective way to only migrate the calendars and nothing else? Maybe a command line option, or a script? I already checked out the occ command, but there was nothing like it in there.
