>I am thinking to make the full image copy of the server from T2000 to T4 and detach the interconnect to put on to new server, node by node
You'd have to get Oracle-Sun to certify and support your plan.

1. First check the Oracle-Sun support for your plan.
2. Take Production Database backup (RMAN Preferably) before starting any activity
3. Check Service Level Agreement (SLA) from the customer before starting the activity
4. if DR is available, make sure that all the archive log files are applied to the standby database.
5. Make the Standby Database ready for FailOver, if something goes wrong for production database while doing the activity.
6. SUN T2000 and SUN T4 architectures are different. So Please read data sheets and available information
Hope it Helps....
Thanks for all information about it. Never done that before and this is production DB... I will log an Oracle SR (support request) about this. Hopefully, we can some definite answer.
Why not add new servers on cluster and remove old servers.
Oracle Clusterware/RAC is designed to do it.
Scalability and High Availability are the main words on RAC World.
"When you combine Oracle Clusterware and Oracle RAC, you can achieve excellent scalability and high availability"
One thing you might want to investigate is the potential impact on your licensing. The Sun T2000 had each core count as 0.25 processors. So a 4-core Sun T2000 would only need 1 processor licensed. I believe that the Sun T4 has each core count as 0.5 processors. The whole point is moot if you license per user and not per processor.
