I am trying to migrate beatrizcabur.com to WPMUDEV. I added the website to the hub and created a new hosted instance, and then installed Shipper on both. The Export from the originating website gets stuck at 66% of the initial checks (I stopped it after 3 hours and half). If I start the Import from the destination website I get this error:
"Error: Service error: status: 508;
Shipper was unable to receive or process your destination’s system package size."
I already followed to the troubleshooting recommendations, but the error is still there and I cannot move forward. Anything else I can try?
