Hi Guys,

My Customer have a CallManager 7825I2 configured with the version 5.1.3 and I would like know if is possible to do upgrade to version 7.x or 8.x.

Thanks,

Hi Wilson,

This is the "master" list for Server support, which does show support for your box in CUCM 7.(x). I would be leery

for 8.(x) as the server support list is not fully fleshed out yet;

Supported Cisco Unified Communications Manager  Releases by Server

It might not be supported for version 8 according to Cisco Compatibility Matrix at

http://www.cisco.com/en/US/prod/collateral/voicesw/ps6790/ps5748/ps378/prod_brochure0900aecd8062a4f9.html

Looking under note 5 at the end of the page, seems like only bridged upgraded is supported.

If you go to version 7 a memory and/or disk upgrade may be mandatory for support, but your client probably will have to spend more money to upgrade again to v8 and on hardware. If it's possible for the client to get new MCS bundle quote and compare prices a better decision can be taken.

Also, keep in mind age of hardware and if it's advisable to replace it as it ages. There is no rule to it, depends if you have redundancy, support contracts for the client's servers.

Excellent point.   If you are spending all this money and time on the upgrade, why not buy a new server and do it right the first time.   If you have to migrate to new hardware next year because this is when they are planning on buying a new server, it will cost them X dollars more on top of what they already spent.  Its basically a new install when you buy a new server.

Figure 2 hours per server just for the baseload.

Figure DRS backup and restore 6 hours (messing around with SFTP, uploading data, etc

Figure another 2-3 hours of testing after the restore.

Figure 1+ hours for phone upgrades.  Even though they say they wont upgrade, they always do something that takes longer than it should.  If they are remote, triple the time.
