[cisco-voip] R: CUCM6.1.4 Upgrade to 8.6.X on New Hardware

[Alice Borgo]

Hi Joe,

   License will be uploaded only on MCS server with Supported Hardware.

 

 

The VMware environment need me only to create a copy of Customer Cluster in
version 6.1.4, enabling me to import the DisasterRecovery DB, and after that
to migrate to final version 8.6.X

 

When in 8.6.X with DR i will export again DB.

 

Install on MCS supported hardware the same version 8.6.x, and import the DB

 

After all check, upload all license file.

 

What do you think about it?

 

Also understood the problem of the SUB, It will necessary upload all audio
files and Firmware phone.

No problem with certificate because no security and no LDAP sync actually
used.

 

 

Thank you for the reply.

 

Regards

 

Alessandro

A few things to point out.  Installing or using any non 8.0.3 CUCM version
on VMware is unsupported.  I've personally seen issues with the license
manager service when putting a pre 8.0.3 CUCM version on VMware as you're
looking to do, even after upgrading it to 8.x!  The supported method
requires an upgrade on the current MCS server to an 8.0.3 or later version,
backup, restore to a VM running the same exact version.  That's why we
created bridged upgrades, so that you can install 8.x on hardware that
doesn't support it, simply to take a backup to move to VMware.  

 

Adding to Abebe's reply, also remember that any custom TFTP files or MoH
files will be lost using the rebuild method for the subscribers and letting
them replicate.  Remember to put back MoH files on the subscribers and
custom TFTP files, and even certificate loaded on the OS admin page for
secure LDAP connections, etc.

 

Again, I'd highly recommend not using the 6.x on VMware method.

 

Joe

you can install the subscriber directly on new hardware it will replicated

Hi guys,

   I need to Upgrade PUB + ONe SUB from 6.1.4 to 8.6.X on new MCS Hardware.

 

Customer want upgrade without modification on the actual Cluster, so I can't
upgrade in place the cucm 6.1.4.

 

 

So using VMware infrastructure i made an exact copy of the 6.1.4 customer
cluster.

 

Using Disaster Recovery export all PUB configuration from the Production
Cluster and imported on the VMware copy.

 

Afeter that I'll proceed with the upgrade step 6.1.4 -> 7.1.5.33900-10 ->
RefreshUpgrade -> 8.6.1.2000-1 on the Virtualized environment 

 

After that Using again DisasterRecovery export DB of the virtualized PUB and
the Import again in the MCS Hardware PUB.

 

Question for you!

 

Need to make the same for the SUB, or is possible to install the SUB
directly on the MCS Hardware without all the upgrade step ?

 

Thank you very much

 

Regards

 

Alessandro Bertacco
