I need to upgrade CUCM clusters from 126.96.36.1990-10 to 8.6.2a.
I used the refresh upgrade procedure described in the release notes of 8.6.2a.
We have to kind of hardware 7835-H1 and 7845-H2
Theses hardwares are compliant with 8.6.2a for bridge upgrade (according to http://www.cisco.com/en/US/prod/collateral/voicesw/ps6790/ps5748/ps378/prod_brochure0900aecd8062a4f9.html)
I try the procedure on MCS-7835-H1.( Not possible for me to make a try now on 7845-H2)
The procedure consists in
- disable extention mobility
- upgrade with ciscocm.refresh_upgrade_v1.1.cop.sgn
- upgrade to 8.6.2a
During the upgrade 8.6.2a I get the following error :
I try the recovery dvd option F (8.6 or 6.1.4) but after reboot I still come back to this screen .
Does anyone get this message (Get a new version of e2fsck) during an upgrade ?
Have anyone done a similar upgrade 6.1 to 8.6 ? does it succeed ?
I open a ticket (SR 622110055)
They tell me that the 7835 is normally Ok for upgrade to 8.6 but they have other tickets with same difficulties...
So documentation is perhaps not exact.
For me, I try the procedure on a DL 380 G5 and it was Ok.
