You have a Drupal website at http://your-old-domain/ and it has to be moved to http://your-new-domain/
you have a Drupal website at http://yourdomain/subfolder1 and it has to be moved to http://yourdomain/ or otherwise to http://yourdomain/subfolder2
To make this work properly there are a number of steps that have to be taken. I can physically move the website to the new location and ensure the website, including menu and permalinks, will work properly.
If you have a lot of pages with manually made internal links pointing to the old location which won't be automatically changed with this process, then I can tackle the first 10 pages or posts to fix this for you.
