Replacing / Updating Website Advice

Hello all, I’d just like some advice on something I’m about to do in-case there is any hidden gotchas I might be missing.

I’m doing some updates on a website. It uses ACF. Most of the updates are straight forward. The last part is adding a new repeater section to showcase projects.

I’ve exported the site using the all in one migration. Imported to Local WP. I’m going to make my edits and then reverse the export/import proccess.

Sounds straight forward to me, would there be anything I’m missing or need to be aware of that I may of missed.

Any help appreciated – thanks.
