This worked pretty well for me, although constructing the cli command took a little elbow grease. This video proved to be very helpful.

Here’s the commands I ended up using:

Testing Upload Process

Before performing the actual upload, test the process with this command:

immich-go.exe -server http://[server.ip:port} -key [put your apikey here w/o brackets} upload -dry-run -google-photos takout-*.zip

Actual Upload

Once testing is successful, perform the full upload:

immich-go.exe -server http://[server.ip:port} -key [put your apikey here w/o brackets} upload -google-photos takout-*.zip

Remove Duplicates

If you’ve previously uploaded photos before syncing your phone, remove duplicates with:

immich-go.exe -server http://[server.ip:port} -key [apikey} duplicate -yes
