Any way to preserve bacteria going from salt to fresh?

[Deadeye]

Like the title says. I’m turning my marine qt into a freshwater qt for a bit while I’m getting Amazon puffers. Besides waiting a couple dozen years and slowly evolving the bacteria, is there an easy way to turn the bacteria from salt to fresh (is it the same in both or am I crazy)?
If not any way to do a super quick cycle? I plan on using some water and decor from cycled tanks, I’d imagine filter media would be better (how do I even transfer that?).
Thanks for the help!

Different bacteria. Bacteria is sessile so gravel, Ornaments and bio media will all have bacteria on them .

I think it's the same but the transition will probably kill the bacteria that is acclimated to salt. Do I know this for certain no.
Mb7 is good for fresh or salt I've used it in both with good results.

Thanks! I’ll continue with my current plan then. Sucks that there can’t be a bacteria species easily transitionable.
Time to grab a lot of crap out of my tanks lol.
