Technically, that should not be a problem. The only thing to foresee would
be that, if you are upgrading to fix any BUGs or CVEs, then downgrading
would revert the fixes.
Just curious to know - when you say downgrade, do you mean to say there has
to be a back-out plan in place if the upgrade fails ? or you are really
going to downgrade again ?
