Time Machine after Mojave installation

[Wando64]

I have just installed Mojave from Sierra on both my Macs and I am wondering whether I should just let Time Machine continuing backing up over what was already there from Sierra, or whether it is better to erase the TM disk and start again.
Opinions? Thanks.

If you have no problems, simply continue. That way you have backups going back as far as the drive allows.

Note, that some had issues after the upgrade and had to start new TM after reformat. But in my case, both TM disks are fine after upgrade and so I can go back over a year on one of them, if I happen to need a file from that far back.

No reason to start over. Why lose all that backup history?

Agree 100%. Got 4 mac devices with 3 different OS versions. Give me chance to rollback if issues occur.
