Chapter 8. Upgrades

Now that you have played around with the new BES and have got accustomed to it, if you have any previous versions of BES you are properly itching to upgrade them to BES version 5. You would have noticed that there are new features and components to BES version 5. In this chapter, we are going to have a look at the process of upgrading previous versions of BES.

Upgrading from supported versions

You can upgrade to BES 5 from the following versions:

  • BES 4.1 with SP3 or later.
  • BES 4.0 with SP7 or later. If you have more than one BES instance in the BlackBerry domain then you will need to upgrade to BES 4.1 with SP3.

All other BlackBerry Enterprise Servers need to be upgraded to either of the preceding two versions.
