Upgrading an IBM MQ installation on Linux

You can upgrade an IBM® MQ installation on Linux® systems without uninstalling the earlier version.

Before you begin

The version that you are upgrading from must be IBM MQ 9.2.0, or later.

[MQ 9.4.0 Jun 2024] If your current version is at IBM MQ 9.4.0 or higher, you can upgrade your installation with fix packs installed. That is, the fix pack number in the version.release.modification.fixpack (V.R.M.F) release identifier does not need to be 0.

If your current version is earlier than IBM MQ 9.4.0, you can upgrade only if no fix packs are installed. That is, the fix pack number in the version.release.modification.fixpack (V.R.M.F) release identifier must be 0.

About this task

You can use rpm, a Debian installer on Linux Ubuntu, or the dnf installer on Linux Red Hat®.

Before you begin, ensure that you have backed up your data.
