Hyper-V upgrade issue from 2.4.5 on a GEN2 machine (solved)
-
Just a note for others out there. I attempted to upgrade a GEN2 2.4.5 -> 2.5.2 which appeared to initially upgrade but got caught in a bootloop.
- created second GEN1 VM with identical NIC and MAC
- exported backup from pfsense without RRD but with all my package info
- created small VHD with backup XML exported in 2 (as per https://docs.netgate.com/pfsense/en/latest/backup/restore-during-install.html )
- installed PFSENSE 2.5.2 on new VM with VHD attached as above
- after first boot I needed to cancel the package update after 30 mins as the logs didnt advance and I had my internet back already.
- ACME hadnt installed (I dont use acme so I installed then removed). Snort and PFblocker both worked.
- no further configuration was needed. Ive cold storaged the 2.4.5 VM
- remove the VHD with config file so that it wont be reapplied on reboot (losing future changes)
hope that helps anyone, it was painless for us.
