I transferred gravitynotes.com and gravitynotes.org from BlueHost over to Namecheap.
For hosting I rented a VPS on Linode.com for $5/mo with 1cpu, 1GB of memory and 25GB of SSD storage. I added the option for 100GB for $10/mo, which is mounted on /var/www.
The static files from the old host for gravitynotes.org have been migrated to the new VPS. Https has been enabled for the domain. And gravitynotes.com redirects to gravitynotes.org.
Email download for backup is finally complete. The result was a 1GB zip file with the contents. I have the file scheduled for upload at 2am Japan time to make the best use of bandwidth.
