    Upgrade path for Informatica PowerCenter

    Thiru Murugan U Active Member

      Hi All,

       

      Can we apply 64 bit hotfix4 on top of informatica 9.6.1 32 bit?

      Can we upgrade the informatica 9.6.1 hf4 32 bit to Informatica 10.2 64 bit in windows.

      Please let me know in case if anyone has achieved this in your project else any pointers will be very helpful.

       

      Thanks & Regards,

          No you can't do...... You need to keep in same bit all include clients also.  You can do by taking backup of domain and Repository etc from 32 bit and do fresh installation in 64 bit and try to import the backups.

            Hi Sree Naga Pradeep,

             

            Thanks for sharing the Information.

            I have one more query.

            Can we restore back up of informatica 9.6.1 as we have applied 64-bit hotfix4 on 32 bit 9.6.1.

            If we restore whole backup, will it restore to 32-bit 9.6.1 without rollbacking HF4 64-version.

            Kindly suggest on this.

             

            Thanks & Regards,

              Each backup file can be restored by each installation of the exactly same software version, no matter whether it's a 32-bit or a 64-bit installation and no matter what is the OS platform for the Informatica platform.

               

              That means you can - for example - safely restore a backup file created with 32-bit 9.6.1 on Windows in a 64-bit installation of 9.6.1 on Unix, no problem at all.

               

              However, applying a hotfix MAY cause trouble. You can restore a backup file only if the repository version has not changed. Please consult e.g. the following article for information about repository versions based on software versions:

              Support

               

              In your case this article shows that all 9.6.1 hotfixes use the same repository version, so you should be good to go here.

               

              Regards,

              Nico

                Hi Nico,

                 

                If we try to choose the roll back option on Informatica 9.6.1 HF4(64 bit) will I get previous version of Informatica 9.6.1 (32 bit).Let us know if any challenges or issues  when we perform this rollback.

                 

                Regards,

                  That can't work this way, as mentioned by Sree Naga. You have to install the 32-bit and the 64-bit versions on different machines, you can't run them on the same machine as an upgrade, no way.

                   

                  That means that during the migration phase you will need two distinct installations, namely the 32-bit installation and the 64-bit installation. Run them in different Informatica domains, any other way will get you into trouble (in particular if you do have to roll back).

                   

                  Last hint from my side: run that whole upgrade thing in a "playground" environment. This way chances are good that you will encounter all possible troubles in this sandbox environment and won't encounter them during the "real" upgrade/migration.

                   

                  We just had to roll back our own upgrade from 10.1.1 to 10.4.1 this weekend, and it was the second time that the upgrade had to be postponed. So please trust me, this is real-life experience and no "joke".
