On some platforms, a 64-bit version of Adaptive Server is available. For some platforms, this is the only version available.
Adaptive Server version 12.5 and later allows you to create a server that uses a logical page size larger than 2K. See What’s New in Adaptive Server? for more information.
Table 3-1 describes the steps for migrating Adaptive Server in both cases.
| Type of migration | Methods/tools available | 
|---|---|
| Pre-15.0 32-bit server to 15.0 64-bit server | You can use the sqlupgrade utility. 
 | 
| 15.0 32-bit system to 15.0 64-bit system | Create a new 15.0 installation and use bcp or dump and load to move data into the new server. You can also manually replace the binary to change to a 64-bit system. See the installation guide for your platform for more information. | 
| Pre-15.0 2K page server to 4K, 8K, or 16K server | Changing Adaptive Server’s schema from one page size to another is a database migration rather than an upgrade. See Chapter 6, “Migration Utility” in the Utility Guide for information about migration. |
