Upgrading to Cisco UC 9.1 - DRS after Upgrading

Hi,

i´m wondering if anyone can explain me the reason for this procedure in the 9.1 upgrade guide:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/elmuserguide/9_1_1/license_migration/CUCM_BK_CBF8B56A_00_cucm-license-upgrade-guide_chapter_010.html#CUCM_RF_DBA280B6_00

There is a statement that we have to do the upgrade to 9.1, do a drs backup and then install the whole thing from scratch!

I see a lot of problems and a tremendous amount of time for the upgrade.

I spoke to my vmware guys and no one can understand why we not only upgrade the virtual hardware and vmtools and that´s it.

Best regards

Steffen

Hi Steffen,

I'm not sure of your upgrade path, but the one linked above

assumes a migration from MCS hardware to Virtual build

as part of the listed process. This is shown in this step (Step 6);

After the DRS backup is complete, shut down the  existing cluster to avoid any conflict with the virtual installation of  the cluster.

So, if you are already running on a VM build this would not be applicable

Cheers!

...ok.

I was confused about the steps mentioned in the upgrade guide, expected something new...

And in fact i´m not a native speaker...;-)

...than it´s the way we have done it for years.

So i can relax and have a beer ;-)

Thanks
