I have been tasked with implementing a patching strategy on our new SLES 11 SP3 boxes which starts patches in test then a month later installs those same patches in production. Rinse and repeat.

Being new to SuSE administration I've started investigating this effort with the Online Update tool. First glance it appears I can select the needed updates, export the list of updates to a text file then install. I'm guessing I can use the text file to ensure only the prior month's patches are installed on production. In the end this solution feels kludgy and error prone so I'm looking for suggestions.

I'm curious how others are pushing patches through their environments and better implementation ideas for this particular scheme of patching test, waiting a month then patching production.

Cheers
Chad
