Upgrading from
BES5
to
BES12
in a new domain

  • To upgrade from
    BES5
    to
    BES12
    in a new domain, install a
    BES5
    instance on a new server (to do this, you need another SRP, an authentication key, and CALs).
  • Install
    BES12
    version 12.5 on the new server. The
    BES12
    setup application upgrades the new
    BES5
    BlackBerry Configuration Database
    to a
    BES12
    database.
  • Next, use
    BlackBerry Enterprise Transporter
    to move the IT policies, profiles, users, and devices in increments from the original
    BES5
    to the
    BES12
    database on the new server. Service interruptions occur only for the batch of users that you are moving from the original
    BES5
    database to the new
    BES12
    database.
Choose this option if:
  • You want to retire existing
    BES5
    instances
  • It is too time-consuming to upgrade existing
    BES5
    instances to
    BES5
    version 5.0.4 MR10 or later

Pros

  • The ability to have
    BlackBerry
    OS (version 5.0 to 7.1) devices supported in
    BES12
  • You can move data at your own pace
  • No impact to the existing
    BES5
    environment

Cons

  • You must build a new
    BES5
    domain
  • You must install another server
