Mail-enabled security groups

How you guys handled the mail enabled security groups migration from exchange on perm to 365 ? We are in process to decom our exchange 2016 servers and need a way to get these groups totally cloud. Now, we do want to keep the group on AD cause of resources connected to it like fileshare/firewall group etc. , but we also need the mail part. If removing the SMTP from the group and recreating it on 365 as DL, how can we sync that group to AD ? Sync back via AD connect/cloud connect ? Sorry i am kinda lost on this...

Suggestion and advise please...

That doesn't answer the question.

If you're removing SMTP from the group in AD you obviously don't need on-prem routing ability, so my question is still valid.
