Migrating to Sybase Adaptive Server Enterprise 11.5 4-3

Adaptive Server Enterprise 11.5 Determine Migration Approach

➤

Note

This migration guide does not cover other parallel migration approaches;

such as, running two systems in parallel where you have to maintain both

the systems simultaneously, or transaction duplication where you use one

front-end to drive two parallel back-ends. These system operational

approaches include factors too site-speciﬁc to detail effectively in this guide.

Whenever possible, upgrade test and development databases release

11.5 ﬁrst. Upgrade the production system after testing. See Chapter 7,

“Test: Ensuring Stability and Performance” for more information about

testing.

Parallel With Replication

The issues for the parallel (with replication) approach are described

in Table 4-2: Parallel migration:

Table 4-2: Parallel migration

Issue Recommendations and Tips

Method Install a new copy of Adaptive Server 11.5

Copy in or load pre-release 11.5 databases t

Use Replication Server to maintain both sets of databases. The release 11.x

system becomes the primary server, and you maintain the pre-release 11.x

system as a warm standby.
