Current Siebel 22.214.171.124 environment is in Windows 2003 Server (32-bit) and planning to upgrade to Siebel 126.96.36.199 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 188.8.131.52 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 184.108.40.206 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 220.127.116.11 to get a successful upgrade to 18.104.22.168?
Can I directly install 22.214.171.124 upon Siebel 8.1.1?
