Assuming we do do the migration first, how would you suggest we subsequently enable replication? Can we just start the sync_client doing rolling replication, or should we do an initial replication of all users by running sync_client manually with a list of users? -- Gavin Gray Edinburgh University Information Services Rm 2013 JCMB Kings Buildings Edinburgh EH9 3JZ UK tel +44 (0)131 650 5987 email gavin.gray@xxxxxxxx -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336. -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336. ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
