Applying patches and upgrades

Migrate for Compute Engine version numbers are in the form:

• 4.major-version.minor-version

You can use Migrate for Compute Engine tools to patch your product installation as part of upgrading to a new minor version of your current major version.

For example, you can apply a patch to upgrade from version 4.11 to version 4.11.1, where version 4.11.1 is considered a new minor version. Use the Migrate for Compute Engine Manager to download and install the upgrade package.

While you can have migrations in-progress during upgrade to a minor version, you should perform the upgrade during a maintenance window when no migrations are occurring. Also, you will be unable to initiate new migrations during upgrade.

Note:

There is no upgrade path to a new major version of Migrate for Compute Engine. When upgrading to a new major version, you must uninstall your current version and then install the new major version.

For example, if you are upgrading from version 4.10 to version 4.11, where 4.11 is a new major version, you must uninstall version 4.10 and then install version 4.11. After installation, you must recreate your migrations because they are lost during the uninstall.
