Upgrade CUCM 8.5 to 8.6

Hi to all,

 I have a customer who would like to upgrade its CUCM from 8.5 to 8.6 (I don't know why he wants it), somebody knows when I do a upgrade from CUCM 8.5 to 8.6, all the configuration remains and is valid for the new version? Is a minor upgrade?? How many improvements have the 8.6 about 8.5 version??

In the cisco site, all documentation for the 8.5 version is the same than the 8.6 version, but I didn't find any documentation for this purpose. All the documentation that I can find is about the upgrade from 4.X or 3.X version. 

Somebody can help me?? If you could leave me a link to a document or website I would thank you a lot.

Thanks to all!!

Babi,Please note that even

Babi,

Please note that even though this is a minor upgrade, this is a refresh upgrade and leads to long down time due to several server reboots. Recommended practice for this is as follows

  • Perform a DRS back up before upgrade
  • Track console of server to monitor progress of upgrade – IP KVM, HP ILO, or IBM RSA
  • Install the latest COP (ciscocm.refresh_upgrade_v1.1.cop.sgn) file to allow for successful upgrade and limit switch version after upgrade
  • To minimize downtime, upgrade Publisher or first node until completion and then upgrade first set of Subscribers or secondary nodes while leaving some nodes performing call processing
  • Select automatic Switchover to the new version
