Instances on different patch levels

  • Hi Folks,

    I have a SQL 2005 Standard 32 bit instance that is on the RTM release (1399). I cannot patch it now as it is a production box I have inherited and staff that use it want to test the patch level on a test database before releasing it to prod.

    To create a test environment I want to install another instance on the same server and update it to (9.0.3073). Can I update this instance and still leave the production one on 1399?

  • Possibly. Not sure if that patch hits shared components or not.

    Why not setup a separate instance on another test machine, or even in a VM? I wouldn't gamble with production.

  • Considering I will need to install SP2 to install it - I think it would. Which are the component that are shared? - perhaps the current instance does not have them. If I configured the instance for different IP would it still regard shared components are shared?

  • I wouldn't put another instance on a production box in the first place.

  • - You'd indeed be better off putting your test instance at another server (not on your production box)

    - You may even consider installing a developer edition (not that $$)

    - If you install another instance on your production box, keep in mind that it will upgrade the shared objects to sp2 and you may even need to reboot the server !!
