It’s really difficult to migrate the CakePHP version from 1.x to 4.x as you’ve to migrate your application sequentially like, 1.x to 2.x, 2.x to 3.x and finally 3.x to 4.x. There’s no automated tool or anything that ease this process. Migration from 3.x to 4.x would be easier because of rector.

So I suggest you rewrite whole codebase to 4.x and start from scratch, that’s would be easier IMHO.

Basically everything that goes for upgrading from 1.x to 4.x also applies to upgrading from 2.x to 4.x. The upgrade from 3.x to 4.x is fairly easy, but upgrading from anything before 3.0 is pretty much going to be a rewrite.

Just my opinion for a gap that large I would probably do a new install and just work on migrating code over.

Also if you are not that familiar with the 4.\* yet, you could work through one of the tutorials to get used of the major changes.
