Typo3 Migration 7.6 to 9

Question

To migrate from Typo3 7.6. to 9, do I have to make an intermediate step via Typo3 8?

I have a Linux Server and the current PHP is 7.0. PHP would be updated as well.

Would like to get to the current version of Typo3 but not sure if a direct jump would cause more problems. (This is aided by an agency, but would like to get second opinion whether intermediate step makes sense)

Answer 1

You should always do an upgrade step by step. It's also good to have this step for all the DB migrations and some manual stuff like raising PHP version.

Answer 2

Depends on the extensions and the level of your knowledge. I would also prefer the step from 7.6 to 9/10 via 8, but if the Extension is still from pi Age or early extras, i would prefer to rebuilt it from the scratch, also because of changing db routines and other depreciation stuff.
