The 2.8TB database must be moved to a new server in a new Data Center,
and upgraded from 8.4.17 to 9.6.6
Will this work?
pg_upgrade
--old-datadir "CURSERVER://var/lib/pgsql/data"
--new-datadir "NEWSERVER://var/lib/pgsql/data"
--old-bindir "CURSERVER://usr/bin"
--new-bindir "NEWSERVER://usr/bin"
Or must I:
1. temporarily allocate 3TB of scratch space on the new server,
2. install 8.4 on the new server,
3. install 9.6.6 on the new server,
2. rsync CURSERVER://var/lib/pgsql/data to
NEWSERVER://var/lib/pgsql/8.4/data, and then
3. pg_upgrade?
Are there better ways? (The pipe from current DC to new DC will be
10Gbps.)
it's a big step from 8.4 to 9.6... If you can do that with a downtime i
would prefer dump & restore.
A solution without (big) downtime would be replication with slony or
londiste.
