unity upgrade/rebuild

[mark.carroll]

hi everyone

I have to upgrade unity 4.2 to 5.x over the weekend, Im wondering is it more straightforward to just rebuild it, keeping old messages is not important so I figured maybe a clean build would be easier?? Im not familiar with the process though so just wanted to check which was best option

Also Im going to take the server off site to rebuild and then bring back to site when finished, i will be rebuilding with same ip address etc but wondered is there any important information I need before rebuilding or should it straight forward to get the newly rebuilt server working with the original callmanager again??

thanks

You can build the new server and just migrate the info with COBRAS. You'll get a fresh install and the info from the old server.

ok so all going to plan I should literally be able to restore from cobras backup onto newly build ver and plug back onto network? am I missing something, I thought this would be a bit of a nightmare...

Pretty much, if the stuff COBRAS does not backup is not something you really need, you can use the tool.

Otherwise it would mean building the new server with exact same version for DIRT restore and the upgrade.

All this is from the help file

Usage Scenarios

This is not a comprehensive list of uses but is  intended to demonstrate the targeted uses of COBRAS in the field.

Straight backup and restore

COBRAS can be used for simply backing up all  subscribers, call handlers, schedules, distribution lists, interviewers and routing rules  and restoring them to a clean install of Unity or Connection after a  failure.  For just plain backup and restore  scenarios where the version of Unity is not changing, however, DiRT (for Unity or  for Connection 1.x) or DRS (for Connection 2.x and later) is the better tool  since it’s faster and includes data COBRAS does not such as COS objects, name  lookup handlers and holiday information.  See the Data  Not Backed Up section for more details on what’s not included with COBRAS backups.

Restore onto a different version or product (migration)

COBRAS is unique in that it can take backed up data  from a Unity 4.0(5) and restore it to a Unity 4.0(5) or later system.  COBRAS can also move from Unity to Unity Connection 7.0.  There are, of course, some items that cannot go between versions and products given the differences  in features and data structures across them.  Be sure to review the details in the Data  Backed Up and Restored section below to understand what’s potentially lost when going across versions  or products.

NOTE:  When restoring a Unity backup to another Unity installation, the version can be different but must be later than  the version backed up.  You can restore to the same version or later only, you cannot restore to an older  installation of Unity.  See the Version  Support table below.
