upgrade windows server 2012 R2 to windows server 2022

in flag

we want to upgrade our windows server 2012 R2 to windows server 2022, looks like we would have to do a clean install.

I have some hard drives (HDD & SSD) which have data, if we remove all the data drives, install windows server 2022 on a new drive and connect the data drives back to the server, would the drives be recognised by the new windows server version? or we would need to format all data drives and restore them with a backup post the server upgrade.

Any help on this would be really great, Thanks.

Yes, any (supported) Windows Server will recognize any NTFS/ReFS/exFAT volumes. Even when attached later.

When using a standalone server and not a domain member, you may need to reset your NTFS ACL on it, though.

2012R2->2019->2022 is an allowed path using inplace-upgrades (this does not require a server 2019 license). Normally, forums are full of warnings "don't you dare to inplace-upgrade", while my experience is very good (do that all the time). If this server is easy to reinstall cleanly, of course a clean setup is always preferred.

My apologies. Just learned by trying that you may even upgrade directly 2012R2->2022!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
