I have used ispconfig_update.sh and now i'm running SVN so i cant do it that way?
No, as this would be a downgrade then. In your case, you will just have to run ispconfig_update.sh again and select SVN again.
Please be aware that running a svn version on production systems in not recommended. You should consider to switch back to the next stable version (3.0.2) when it gets released in a few weeks.
