Hello,
After upgrading from Sierra 10.12.6 to Catalina, can I just continue my Time Machine backups (3TB ext. HDD, HFS+ formatted)? Will new files simply be added to the timeline of existing backups? Or do I have to reformat the backup drive to APFS and then create a new backup?
Thanks!
Theoretically yes—upgrading from Sierra 10.12.6 to Catalina, can I just continue my Time Machine
At this time TM format continues to be recommend as hfs file format

If your new Mac inherits your backup history - Apple Support
You can move the backup history from one Mac to another, but after the
new Mac “inherits” the backup history, you can’t use the backup history
on the original Mac
If you have the luxury of another drive you can start new.
