Potential for database corruption as a result of installing Exchange 2007 SP3 RU3
I installed 2007 Sp3 and followed it with RU3 on 3/20/11. I had LCR enabled for 3 storage groups- I've disabled LCR for now. I'm not seeing any of the 3 event errors above in the application event viewer. My info stores total about 70gb and I only have 1 exchange server with hub transport/cas and mailbox roles.
If I uninstall RU3, should I then install RU2 since previously only SP3 was installed? Do I have a higher risk of db corruption from RU3 uninstall than if I were to just leave it installed and wait for the re-release of RU3? Finally, when RU3 is released again would installation of it require uninstall of the problem RU3 first or will it just over install?
