Aqua sobriquet

I’ve ordered a new filter for my tank. I would normally just swap the existing Bio media over from the old unit and carry on. I want to change the type of media I’m using though. I have a couple of options. I could run the new filter alongside the old unit until it’s successfully seeded then remove the old filter. I’m not sure how well this would work or how long it might take. The other option is to swap the old media over and as the new filter is larger add the new Bio media in another tray. Again, I don’t know how long it would be best to leave the old media in the filter. Tank is planted 60L with shrimps and six Corydoras. Old media is Siporax and new will be Ziss ZM-11. Any thoughts?
