Current Siebel 188.8.131.52 environment is in Windows 2003 Server (32-bit) and planning to upgrade to Siebel 184.108.40.206 in new OS Windows 2008 R2 Server (64-bit) with Open UI enabled. I have gathered all required information for upgrading this whole environment.
- Siebel apps will still be 32-bit application.
- Siebel enterprise can be installed on 64-bit with IIS 7.5 (with 32-bit compatibility)
I plan to do this:
a. Take a clone of existing Siebel 220.127.116.11 database and name it "UpgradeDB"
b. Install Siebel 8.1.1 in the new Windows 2008 R2 Server (64-bit)
c. Install Siebel tools/Client 8.1.1 in windows XP (32-bit)
d. connect to the cloned database "UpgradeDB"
e. Apply Siebel 18.104.22.168 patch upon existing 8.1.1
f. Execute IRM
g... rest of the steps as mentioned in the bookshelf.
My question is: Should I install all the patches after 8.1.1 upto 22.214.171.124 to get a successful upgrade to 126.96.36.199?
Can I directly install 188.8.131.52 upon Siebel 8.1.1?
If the plan above is not correct, please help!
All the enhancements and fixes from 8.1.1 to 184.108.40.206 will be available with 220.127.116.11.
Installing the 18.104.22.168 patch and executing IRM (If you intend to use Open UI and new features included from the Siebel CRM version 22.214.171.124 innovation pack)
are sufficient to do successful upgrade.
Instead of cloning and connecting to the DB you could create a restore point and use it when needed. Always keep a level 0 cold backup before making any changes to the database
as part of pre-upgrade tasks.
