I don't have anything serious on Google drive, just some files I share with third parties that primarily exist on my network; and certainly no photos. Photos are on my NAS which is backed up on several disks; I publish them on a small app that I built, self-hosted (after years with Smugmug I left them two years ago).

Most accounts with third parties use domains I own that are not on Google in any way. Some still use a gmail address and I need to migrate those. But nothing essential.

That’s helpful context . How do you collaborate ? For example when a customer or partner sends a Google Drive / Dropbox folder for you to contribute to ?
