creating clone of xnat with different fqdn

[markiz dosadny]

Hi

I'm trying to create clone of xnat for test purposes, and in the meantime test migration from stand-alone server to docker-compose.

I came with procedure as follow:

1. I'm spinning up docker infra with same version of xnat and postgres.

2. on old server I'm dumping database to sql file

3. on docker host I'm restoring db with:

   sed 's/xnat.blah.org/dev-xnat.blah.org/g' xnat.sql | psql -U postgres xnat

When I'm trying to login with same credentials as the original one, I got message:

XNAT has encountered an error with your request:

Status Unknown status

URI: Unknown URI

Message Unknown error occurred

Please advise where is error in my small procedure. 

Thanks in advance
