I will have to read up on the changes and incompatibilties it
introduces. Some of my systems use direct file:// access (although afaik
just for checkouts, no commits). So this *might* still be an issue.

The output is as follows:

| % svnadmin info foo
| Path: foo
| UUID: d7ac1088-da18-0410-849e-888fbd42cb43
| Repository Format: 3
| Compatible With Version: 1.1.0
| Filesystem Type: fsfs
| Filesystem Format: 1
| FSFS Sharded: no
| FSFS Logical Addressing: yes
| Configuration File: foo/db/fsfs.conf

Indeed it lists Logical Addressing 'yes'.

As i understand, dump/load-ing also activates the new features like the
'pack' stuff. I have to read in to that and find out what this means for
o(l|th)er clients.

I use svn to commit changes but am not very experienced with the deeper
internals of svn's workings. ;)

Will have to plan a maintenance window then. 
Gah. :)

Thanks for your prompt reply!
