Upgrading from
BES5
to
BES12
in an existing domain

To upgrade from
BES5
to
BES12
in an existing domain, you can install
BES12
on the same computer as or on a different computer than an existing
BES5
database.
Follow the instructions in the
Planning Guide
and the
Installation and Upgrade Guide
for
BES12
version 12.5 to install
BES12
and point it to the
BES5
database to upgrade.
If you install
BES12
on the same server as the existing
BES5
database, make sure that the server meets the hardware requirements for
BES12
.
If you install
BES12
on the same server as the existing
BES5
database, performance issues can occur if the number of users and devices exceed the optimum for a single server environment. To accommodate more than the recommended number of users and devices for a single computer environment, install
BES12
on a separate server, or install additional instances of
BES12
after the upgrade is complete.

    BES5
    database is upgraded
