Yup, sounds good to me!
At this point you need to take all existing working copies of e.g.
trunk and switch them so that they know to point to this new
different path *within* the repository, but that the repository
itself has remained at the same base location:
svn switch svn://server.name/trunk /path/to/wc
Same for any working copies of any branch or tag.

After changing the repository root, you need to do the second kind of
switch, namely relocation. For each working copy of e.g. trunk, fix
the working copy to know that the repository itself has moved, while
the path within the repository has remained the same:
svn switch --relocate svn://server.name svn://server.name/proj1 /path/
Same goes for any working copies of any branch or tag.

As I understand it, the reason for this problem is that, while to you
the URL before and after looks the same, to Subversion, the URL is
divided into two parts: the part that gets you to the repository, and
the part that defines the path within the repository, and you've
changed both of these parts. For the change in the path within the
repository, you need to execute a "switch"; for the change in the
part to the repository, you need to execute a "switch --relocate".
Or, of course, you can just check out new working copies.
