is use first to validate readiness of Adaptive Server 15.0.2 for downgrade.
is used after prepare parameter when ready to proceed with the act of downgrading to a previously installed 15.x version of Adaptive Server. Server must be in single user mode. (started with -m option)
can be 15.0 or 15.0.1 written “150” or “15.0”, “1501” or “15.0.1”
specifies verbosity. Valid options are 0 (for no) or 1 (for yes).
specifies whether to skip databases that are not writable at this time. Valid options are 0 (for no) or 1 (for yes).
This is an example of the output from running sp_downgrade.

Use to revert to the previously installed Adaptive Server 15.0.x release. At this time it is not possible to revert to Adaptive Server 15.0.2.
When downgrading to a version of Adaptive Server earlier than 15.7, the sp_downgrade system procedure internally calls sp_passwordpolicy [ prepare | downgrade ] along with the Adaptive Server version number to downgrade.
When you execute sp_downgrade, Adaptive Server performs these tasks:
Truncates role passwords and locks roles.
Removes newly added attributes in sysattributes under class 35.
Removes newly added class 35 in sysattributes.
Removes the new locksuid, lockreason, and lockdate columns from syssrvroles.
When you downgrade Adaptive Server version 15.7 to a
pre-15.0.2 version, both role and login passwords are downgraded.
When downgrading to version 15.0.2, however, Adaptive Server truncates
and locks only role passwords.
For more information about downgrading role passwords, see the downgrade section of the installation guide for your platform.
The permission checks for sp_downgrade differ based on your granular permissions settings.
Granular permissions enabled |
With granular permissions enabled, you must be a user with sa_serverprivs_role and sybase_ts_role. |
Granular permissions disabled |
With granular permissions disabled, you must be a user with sso_role and sa_role and sybase_ts_role. |
