Not necessarily, if there are errors in sam.ldb, these will just
replicate to the new DC.

No, if you want to transfer all the fsmo roles to a new DC, you can use:

samba-tool fsmo transfer --role=all -UAdministrator

If you can upgrade via distro packages, then this is the way to
upgrade. If you want to upgrade to a later version that your distro
doesn't supply, then it is probably easier to create a new DC to
replace the old one.
