Replacing Unity Hardware

Unanswered Question

Hello,


Good Day everybody.


We have a client who is willing to upgrade/replace the current hardware on which Unity server reside with up to date Cisco MCS 7845 servers. Client has 2 Unity Server's in failover and one off box exchange server. We have Unity 5.x installed and would be the same version after the upgrade.


I am reading the replacing and upgrade guide for Unity and it is saying use DIRT and restore the backup on the new server. There is no information on how to upgrade the off box server.


Can some one help me here? Has anyone done this before?


Does the replacing and upgrading guide procedures are good enough to follow or there are any specific i need to follow?


Please help...


Thank You

Yogesh

Assuming you are doing the following:


Existing platform is Unity 5.x on Windows 2000


New hardware has been purchased.


You can probably do the rolling upgrade procedure.  I used this to replace the OS on a few Unity clusters and it works fine.

DIRT backup the failover

Shut down the primary

Stop the WWW services

load the new server with windows 2003,

join the domain

install SQL and service packs

run the Service Pack disc for Unity

Load Exchange Admin pack and service packs

Load unity

load any unity ESs from previous load

DIRT restore

rerun failover

bring primary back online.


For the failover, its pretty much the same, other than you dont have to do a DIRT restore. Just rerun failover and on the secondary server and it should replicate the database.


Same hostname, Same IP address.  No changes or it will not work.


enjoy

If the version will be the same after hardware upgrade then TCat has you covered.
