I might have found a workaround if no one else has any other idea. This site (multcloud.com) is for transferring between clouds. - Source: Reddit / 4 months ago
I have tried multcloud.com, cloudsfer.com end some minor ones. None of these are accurate IMHO. They are not able to move all contents leaving me with an issue to check hundreds of items. Also they do not provide a simple feature: move ALL from A to B, period. I do have loose photos and many Albums I would like to preserve. Sadly, Google Drive desktop client is not able to create Albums based on directories. - Source: Reddit / 8 months ago
If you haven't seen mention of it, MultCloud is amazing, and can sync between all kids of services, including to Synology. Set mine up within a few minutes. (multcloud.com not a paid or compensated referral). - Source: Reddit / 8 months ago
You can use https://multcloud.com to transfer files from Photos to Drive or directly to Koofr via WebDAV. - Source: Reddit / 9 months ago
