Test-server (without replication) available well in advance to exercise normal operation by developers, NRI, build-farm, … allowed to identify more suitable directory structure tested fixes for code referring explicitly to CVS administrative files some Makefiles assumed particular file-permissions on binary

files, while SVN deals with that in a different way

After migration and enabling replication few WANdisco cases (talk-back script, logs, address already in

use) SVN client version

Pending: branching strategy / use of trunk

Clear initial involvement of group-lead to decide on the priority of the issue
