Hardware and OS refresh for media server

[Mike_3G]

Currently - I have 2 media servers on RHEL 4 running NBU 7.0.1 and I want to do a hardware/OS refresh to Centos 6, followed by NBU upgrade to 7.5.0.3.

The master server has already been successfully upgraded to RHEL 5.8, NBU 7.5.0.3.

My questions are:

1. If I reuse the IP/hostname for the media servers, do I need to decomission them during the refresh/upgrade process?

2. Do I install NBU 7.5 (and 7.5.0.3) directly on the media server as opposed to the Master Server, where I had to install 7.0.1 prior to upgrading?

Thanks, Mike

No need to decommission. 

I would delete all devices on old servers since all OS device names will be different on new servers.
Next step will be to deactivate old media servers.

Shutdown old media servers.

Install 7.5 followed by 7.5.0.3 on new media servers.
Ensure devices are visible at OS level.

Activate media servers on Master.
Ensure comms with media servers by running 'nbemmcmd -listhosts -verbose'

Start device config wizard on master, select the 'new' media servers.

Check STU properties - update if not the same as previous properties.

And there's no problem with carrying over the old hostname and IP address? Will it affect policies or recoveries in any way?

Sounds easy, though. Thanks, Mike

No problem ... 

If you had /etc/hosts entries for master and clients on old servers, just be sure to add same hosts entries on new media servers.
