Is it safe to delete companyweb,connect, & sbsconnectComputer after migrating AD from SBS2011 to Win2012R2

We updated our network several years back. We are growing now and need to clean up our system before implementing anything new.
I noticed that I have in my DNS manger three entries that carried over from SB2011 into our Win2012R2 deployment.
We have three host records for the following:
It assisgned to an ip that is not active in our network.
It does now show up in network scans, pings, nslookups,.
Is it safe to delete these entries? Is there anything else I need to do before deleting it?

If you are not using SBS 2011 anymore, these can safely be deleted.
They all point to SBS server IP.
Usually there are more than three static records.
Check if more records have an IP of old SBS server.

Agree with Toni.
Yes you can. Just delete them, and that's it. With the SBS server no longer online, there is no reason to be concerned. No special steps or considerations to take into account.

Just removed it from our DCs.

All is good for now.
Thanks you.
