Migrating from 32-bit to 64-bit versions

sqlupgrade upgrades Adaptive Server only from one version to another. This section describes how to migrate a 32-bit version of Adaptive Server to a 64-bit version of Adaptive Server.

To migrate Adaptive Server from the 32-bit to the 64-bit version, you must first install and configure the 64-bit operating system.

Method #1: Dump and load

  1. Run dbcc checks on all databases in the 32-bit Adaptive Server and make sure they run cleanly.

  2. Create a 64-bit Adaptive Server in a new directory.

  3. Create devices and databases to match those in the 32-bit server. Make sure that the sysusages mapping is correct. See document ID #1324 http://my.sybase.com/detail?id=1324.

    NoteAllow 10 percent additional space for the sybsystemprocs database.

  4. Dump the databases on the 32-bit server.

  5. Load the databases to the 64-bit server.

  6. If you have partitioned tables, update partition statistics.

  7. Run dbcc checks on the 64-bit server and make sure they run cleanly.

Method #2: BCP data out and in

If you have DDL scripts to create devices, databases, tables, rules, stored procedures, triggers, and views, you can use bcp to move data out of the old database and into the new.

If you do not have DDL scripts, use the ddlgen utility to re-create the schema for the Adaptive Server you are about to upgrade. See the Utility Guide.

  1. Run dbcc checks on databases to verify data integrity.

  2. Use bcp to extract all the data from all the tables in the databases.

  3. Create a new 64-bit Adaptive Server in a new directory.

  4. Create devices, databases, and tables.

  5. Use bcp to bulk copy data into tables.

  6. Re-create all views, triggers, stored procedures.

  7. Run dbcc checks on the 64-bit server and make sure they run cleanly.
