Moving a site from one account to another in Pantheon
Today I learned there's no automatic way to move a project from one account within Pantheon to another. But the manual way is super simple.
Step 1: In the "from" account, create a backup of the site. It should look something like this:
Step 2: In the "to" account, choose "Import a Site" and then choose "provide separate code, files, and databasde archives":
Step 3: Foreach of code, database, and files, in the "from" account, click the "download" link and copy the "temporary link" it gives you:
Then paste that link in the corresponding field in the "To" account:
Step 4: Push the red, jolly, candy-like button at the bottom and you're on your way.
Protip: When they say temporary links, they mean temporary. Don't start copying your links until all 3 of your archives have been created. The links are only good for a minute or two.
