Migrating Servers and Databases
Go Up to Migrating to InterBase
You can migrate your servers and applications to InterBase 6 at and later different times. They are separate migrations. Bear the following issues in mind as you plan your migration:
- Older clients can still access databases that have been migrated to InterBase 6 and later. You must be aware, however, that they cannot access new data types or data stored as INT64, and they always handle double quoted material as strings.
- InterBase strongly recommends that you establish a migration testbed to check your migration procedures before migrating production servers and databases. The testbed does not need to be on the same platform as the production clients and servers that you are migrating.
The migration path varies somewhat depending on whether you are replacing an existing server or installing a new server and moving old databases there. Upgrading an existing server costs less in money, but may cost more in time and effort. The server and all the databases you migrate with it are unavailable during the upgrade. If you have hardware available for a new InterBase 6 and later server, the migration can be done in parallel, without interrupting service more than very briefly. This option also offers an easier return path if problems arise with the migration.
