Migrating workflow

We are migrating our journal new a new instance and do no want to lose our workflow/ archived of things not published. From reading the forum here, it seems like there is a plugin that might do this, but it needs to run on 2.4.6. Currently, we are at 2.4.4- is it possible to update to 2.4.6 and not 3.0 in order to use the plugin? Does anyone know of other options for migrating workflow?
