Error using Sharepoint Migration tool
So I am using the Sharepoint migration tool to move us from sharepoint 2010 to sharepoint 365. However each time I run it, I get the following Error: Invalid site URL 'https://portal.gwisr.org' ...
Vgoss I've had this issue with a corrupted Site Column and followed this blog to resolve the problem. The migration tool wasn't able to read the one of the Site Columns

I am not 100% sure if you can migrate External Content Types.
The error code indicates it's a site access issue but in my case it was just one item in the site it couldn't access.
