In a PlateSpin Migration Factory deployment, you must upgrade each of your PlateSpin Migrate Servers from version 2019.2 to version 2019.5. You can begin the upgrade for a Migrate server after you upgrade its associated PlateSpin Migrate Connector.
For requirements and instructions, see Upgrading PlateSpin Migrate
in the PlateSpin Migrate 2019.5 Installation and Upgrade Guide.
