MII Upgrade from 12.1 to 12.2

All,

We are currently on xMII 12.1 on CE 7.1 ehp1 system.We have a requirement to upgrade the MII from xMII 12.1 to MII 12.2.

From the guides, I believe the upgrade from xMII 12.1 to MII 12.2 would be as follows.

1) Use CE Update Manager to deploy the XMII00_0, MIIADMIN00 corresponding to MII 12.2 as JSPM cannot recognize these files.

2) Migrate from MII 12.1 to MII 12.2 by exporting the configurations and projects from MII 12.1 and then importing them in MII 12.2 once the MII has been upgraded from MII 12.1 to MII 12.2.

Yes, there are pre-requisites corresponding to JRA and others according to the upgrade documentation.Please let me know if I have missed out on any steps.

But, After the First step, " Use CE Update Manager for deploying MII 12.2", will the existing MII 12.1 be no longer available in the system.

Regards,

Murali Narayanan

    Just a caution when migrating where IDoc or RFC Listeners are concerned. You need to modify one version's Listener(s) using new (and unique) Program IDs. If you try to use the same Program IDs in both 12.1 and 12.2 instances, you will get inconsistent performance (some documents will go missing from one or the other Listener).

      Yes, the upgrade from MII 12.1 to 12.2 needs to be carried out using CEupdate Manager considering the underlying CE system already matches the pre-requisites.

      I was able to perform the upgrade using CEUpdate Manager.

    You can see the list of installed software at some places, but my preferred one is with JSPM. There you can see if the installation of MII 12.2 has removed the installation of MII 12.1 (that seems to be the logic option).
