Here are the steps on how to migrate the Unifi Network Application from a 32bit Pi Bullseye to an 64 bit Bullseye (Raspian Software):
- First you need to check your current version of the Unifi Network Application running on your 32bit Raspian
- Then you need to download the backup Image and save if somewhere safe – NOT on the SD Card you’re about to format 😉
- Clean Install with the Raspberry Imager – 64bit Version
- Run it an check that you have the same IP as before!!
- sudo apt update -> sudo apt upgrade
- install dependencies: sudo apt install binutils openjdk-11-jre-headless
- now you need to check if you have the libssl1.0.0 Package installed with a command: sudo apt list libssl*
- If that is not the case you need to download it: wget http://ports.ubuntu.com/pool/main/o/openssl1.0/libssl1.0.0_1.0.2n-1ubuntu5.11_arm64.deb
- Install it: dpkg -i libssl1.0.0_1.0.2n-1ubuntu5.11_arm64.deb
- Now you can download the Mongo DB (either 3.4 or 3.6 – which I installed): wget https://repo.mongodb.org/apt/ubuntu/dists/xenial/mongodb-org/3.6/multiverse/binary-arm64/mongodb-org-server_3.6.23_arm64.deb
- Install it: dpkg -i mongodb-org-server_3.6.23_arm64.deb
- Next you can download the 64bit Unifi Network Application package but the SAME Version as you had on your 32bit Image
- Download it: wget https://dl.ui.com/unifi/7.3.83-4501ffd244/unifi_sysvinit_all.deb
- Install it: dpkg -i unifi_sysvinit_all.deb
- After that login to https://(ipaddress):8443 and restore it with the backup you downloaded…
- Finished :-)!!
