I have an SVN server running on a very old machine, and I'd like to migrate it over to a new machine. Currently all access to it is via https/apache. If I dump the current repo, copy over the dump and the password file, load them into a new repo on the new machine and set it up for apache/https access as before, will it be seamless for the user? I plan to update the DNS so the old hostname points to the new machine. Only caveat is that I'd like to use fsfs on the new machine (the old one uses berkeley db).

If your question is "If I move the repo, will it be seamless to the user?" The answer is, as long as the host name is he same, the repo path is the same, and the access method is the same, then yes, it will be seamless. If any of that is different, then the user will have to update their remote repository location with the "switch" option.

If you question is "how do I move a repo and will the user notice?" then the latter is answered above, the former can be answered with a note I left for myself after the last time I moved a repo to a new machine:

I don't *think* that the storage type (fsfs vs bdb) matters.
