Migrating to SVN 1.5 on Linux from SVN older version on Windows

This is coming up for us and just wondered if anyone out there has already done this and has any pointers, gotchas, tips, tricks or anything else to contribute to our happiness.

I understand that SVN 1.5 is a fairly major release which incorporates new merging facilities.

We will also need to update the eclipse plugin 'subclipse' that we use to a compatible version. I have started looking at the version we need but think just the latest (1.4.5) will work best. Currently we are using 1.2.4 because we are pointing to our pre 1.5 repository.
