continuing svnsync from svn hotcopy

svnsync can be a time-consuming process if your revision is big. In this case, I will show how to continue the svnsync from hotcopy


1. Backup current by hotcopy
- svnadmin hotcopy /svn/repos/repos1/ /tmp/repos1

2. Copy data(/tmp/repos1) to new svn server directory /svn/repos/ (svn repository root) 

3. (optional) Upgrade SVN version property in case new SVN sever is  newer than old SVN server
- svnadmin upgrade

4. Initial SVN property for start svnysnc 
- svn propset --revprop -r0 svn:sync-last-merged-rev revno svn://hostname/reposname/
- svn propset --revprop -r0 svn:sync-from-uuid uuid svn://hostname/reposname/
- svn propset --revprop -r0 svn:sync-from-url svn://oldhost/reposname/ svn://hostname/reposname/

5. Sync data from old repos to new repos
- svnsync --non-interactive sync svn://hostname/reposname/
