Importing a long lived access token

I’m migrating to a new server and trying to re-install Haaska. It’s the same ip address etc, so all the configuration at the Amazon end should be the same, and I think it is just the token that’s missing.
I know how to generate a new long lived token on the new server, but is there any way of importing the old one from the old server? I have a record of the text string.

I have the same issue
did you solve it?
thanks in advance
