Depending on the filesystem .. you should be able to at least minimize the downtime... and not require an IPL. OMVS is restartable. Just create a new filesystem/dataset, copy everything into it, stop the application and swap the new one for the old one, restart app, copy any missing files from old to new one... then delete the old data set. Downtime should mostly be just the time to shutdown and startup the app.
