We are migrating from one data center to another, all new equipment and the latest Oracle 11gR2 database. To minimize the migration window, I was thinking about using data guard to replicate the production database to the new data center prior to migration weekend.
- Has anyone used data guard to create their new production database?
- Can data guard be used to create a standby database on a newer version of Oracle (source Oracle 10.2.0.5.0 - target Oracle 126.96.36.199.0)?
- Is anyone aware of the ports used by data guard so I can make sure the firewall is open between data centers?
Thanks in advance,
