Thanks @Ed and @JD for your response.
I checked each link you provided JD (thank you so much for keep a copy of them!) and according to them AIX 7.2 was mentioned only on CMOD 10.5. All the others had the "or later" statement like @ED mentioned.
Would you guys just give me a hint about what you think it's better in my case ?
Option 1:
1. Upgrade AIX to 7.2 Base
2. Upgrade DB2 to 11.1.1.1 (it's a supported version for CMOD starting on version 9.5)
3. Upgrade CMOD 8.5 to 9.5 (according to this document:

4. Upgrade CMOD 9.5 to 10.5 (according to this document:
https://www.ibm.com/support/pages/upgrade-guide-content-manager-ondemand-server-v1050#950X)
5. Apply IF10.5.0.3
6. Install WAS
7. Install Navigator
Option 2:
1. Apply TL2 on AIX 7.1 (minimum requirement for CMOD 9.5)
2. Upgrade CMOD 8.5 to 9.5 (according to this document:

3. Upgrade DB2 to 11.1.1.1 (it's a supported version for CMOD starting on version 9.5)
4. Upgrade CMOD 9.5 to 10.5 (according to this document:
