We did for a number of years when we first took Service Desk, but since version 7.5 I think the upgrade has been quite straight forward, and we do it ourselves with little to no input form LANDesk. We test the upgrade on a test system first mind.
Planning our first upgrade to 7.8 without consultancy....slightly nervous!
You guys will be fine.
Test it in your test environment and follow the steps in the upgrade guide. You may find the install guide useful as well.
Make sure you allow a decent amount of elapsed time and if you are moving from an elder release for reasonably extensive testing. The main benefit from having an LD person or partner do the work is they keep up to date with any of the little wrinkles needed and can get them sorted out quickly.
We had a professional services do the initial build out and install of 7.3.2. From there we performed our own upgrades to 7.5, 7.5sp1, 7.5sp1 hf3, then to our current 7.7.1. As DMS mentioned, if you are going from an elder version to a newer release, give plenty of time to test and perform the upgrade itself. Our db was a pretty good size, so our last upgrade, meaning the db upgrade, took quite a while.
We have a very small IT team and consulting budget is zero for technology. We have found the upgrades are pretty bullet proof and generally quite simple in terms of execution (read the upgrade doc and follow).
* If you are virtual - it doesn't get much simpler in terms of pure upgrade.
* Test - and then Test - they upgrade will work - and that is likely what you are paying for. If you have issues in your test environment after upgrading - then use your precious consulting budget if you can resolve via the community or support.
* Honestly - as far as Upgrades go - the product is better than most.
Just a quick 'Thank you' to all of you who replied - much appreciated and encouraged. Sounds like it just has to be done!
