[PULL 21/27] migration: Fix "switchover" used as a verb in comments and docs

["Cédric Le Goater" <clg@redhat.com>]

From: Avihai Horon <avihaih@nvidia.com>

"Switchover" is a noun; the verb form is "switch over".  Replace all
instances where "switchover" was incorrectly used as a verb in comments
and documentation.
