Some people have computers upon which they have successfully performed
operating system in-place major version upgrades; some boast of several
such upgrades over many years. I didn't have much success with this
early on, so I pursued the KISS approach instead. I have invested in
learning and resources that allow me to do image, backup, archive, wipe,
install, configure, restore, migrate, test, commissioning, and cut-over
processes.
I find it helpful to:
1. Have a dedicated hardware firewall/ router appliance.
2. Have more than one computer, each dedicate to one purpose:
a. File server.
b. Backup, archive, and imaging.
c. Workstation or laptop (one user each).
d. Other, as needed.
3. Use HDD/SSD mobile racks.
4. Maintain a supply of spare parts, including a spare computer that
can substitute for any of #2.
It sounds like you have put yourself into a disaster recovery situation.
I'd advise restoring the Wheezy server, building a fresh Jessie server,
migrating the services and data, testing thoroughly, and making a decision.
