allocate a new ip to the server. reconfigure/restart 9.0 to listen on the main IP (not "all" as default) use ezjail to create a freebsd jail on thenew IP install 9.2 in the jail treat it them as two servers. point clients at new ip. once migrated, delete all 9.0 from the main server. if you need to upgrade again, add another jail. stop and delete the old jail whe the next upgrade is complete. repeat as often as you want to upgrade. i'm pretty sure this can be adapted to linux, but i forget what their jail equivilent is. the overhead is minimal -- Jim Mercer Reptilian Research j...@reptiles.org +1 416 410-5633 "He who dies with the most toys is nonetheless dead" -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
