I personally would just get 2022 and transfer the services/data over (without knowing the context). If you need to keep it all running special apps, you'll want to upgrade it to 2016 and then 2019. Backup/snapshot at every step to have a decently fast way to back out should you get any surprises. Remember to download all the latest drivers and firmware first. Good luck.
