MobiLink upgrades

Version 12 MobiLink clients are incompatible with versions of the MobiLink server before 12.0.0.
On 64-bit operating systems, the MobiLink server is only installed as a 64-bit application and must be run as a 64-bit application. Any 32-bit versions of the MobiLink server that might remain on your system from previous version 12 installations cannot be run on a 64-bit system.
The version 12 MobiLink server can be used with clients that are version 10 or later. If you need to support earlier clients, you should keep an earlier version of the MobiLink server to support them.
Confirm that none of the documented behavior changes affect your application. If they do, you must update your application. See SQL Anywhere 12 - Changes and Upgrading.

If you are upgrading an existing MobiLink installation, you must upgrade the components in the following order:

Shut down the MobiLink servers.
Upgrade the consolidated database.

See Consolidated database upgrades.
Upgrade the MobiLink servers.

See MobiLink server upgrades.
Start the MobiLink servers.
Upgrade the MobiLink clients.

The version 12 MobiLink server can only be used with clients that are version 10 or later. MobiLink clients prior to version 10 must be upgraded in order to work with version 12 MobiLink server.

For information about UltraLite applications, see Upgrading databases created with previous versions of UltraLite.

Before upgrading, check for behavior changes that may affect you and take standard upgrade precautions.
