This section describes how to downgrade from Adaptive Server 15.0.2 to an earlier Adaptive Server 15.0 or 15.0.1 release. Downgrading to a 12.5.x or earlier release is not supported. Instructions to downgrade to a 15.0 or 15.0.1 version include:
Basic downgrade steps using new system procedure sp_downgrade.
Post-downgrade tasks.
Information regarding downgrading if you used 15.0.2 features.
Returning to Adaptive Server version 15.0.2.
Adaptive Server 15.0.2 is not an upgrade release if
you are starting from a 15.x version of Adaptive Server. For all
pre-15.x versions Adaptive Server 15.0.2 is an upgrade release.
Also, Sybase recommends that you do not use the new features offered
in Adaptive Server version 15.0.2 until you are committed to staying
with 15.0.2.
Downgrade is only available from Adaptive Server 15.0.2
to Adaptive Server versions 15.0 and 15.0.1. You cannot downgrade
directly to version 12.5.x or earlier. If you must downgrade to
a release earlier than 15.0, you need to restore databases from
dumps made on that older server.
