OK to keep older version for now

With all the updating problems I have just one question. Is it safe to keep the old version. Is that version just as safe as it was before the new version came out[sounds dumb but?]. Does the old[last] version need to update “anything” that might not get through with such demands on the server for the new release I would rather wait it out and update at some future time if that is a safe option.

thanks…

You mean just install the latest release right on top of the old version. That works? and preserves all it has learned and all the rules? Why isn’t anybody reccomending that if it preserves everything?
