问题
I'm about to upgrade a SVN server from version 1.5.5 to 1.6.5 - all is fine with the actual upgrade, but I'm a little confused about upgrading the actual repositories.
I've read in a few places (here, here), that it's better to dump and reload the repositories rather than using svnadmin upgrade. I assume that I should dump, upgrade the server and then load the dumps back in - however, should I clear the old files out of the repository before loading? If so, what's the best way to do this?
If, before I thoroughly screw up my version control system, someone could give me a quick step-by-step, it would be really helpful!
Cheers, Mark
回答1:
there is a quick step-by-step in the Subversion FAQ:
- Shut down svnserve, Apache, and anything else that might be accessing the repository.
svnadmin dump /path/to/repository > dumpfile.txt, using version X of svnadmin.mv /path/to/repository /path/to/saved-old-repository- Now upgrade to Subversion Y (i.e., build and install Y, replacing X).
svnadmin create /path/to/repository, using version Y of svnadmin.svnadmin load /path/to/repository < dumpfile.txt, again using version Y of svnadmin.- Copy over hook scripts, etc, from the old repository to the new one.
- Restart svnserve, Apache, etc.
more details on dumping and loading in the Subversion book. i assume you studied the subversion 1.6 release notes.
回答2:
No, you do not need to dump/load to upgrade, 1.6 was specifically designed to be an easy upgrade using just svnadmin upgrade. I've done it, it worked, I am happy.
The release notes explicitly say there is no need to dump/load the repo.
I would make a backup anyway (just in case), and then do the recommended upgrade. I'd then pack the repo files (svadmin pack) to make future backups quicker and SVN perform faster.
回答3:
If you're going to do it that way then you probably want to dump, upgrade, delete and recreate the repo then load it back in again.
I can't say I've ever had any issues just using upgrade though, although you may end up with a less optimal repo structure.
