Migration from 32 bit to 64 bit appliance – Device42 Support Portal

Here is summary of steps to migrate from 32 bit Device42 appliance to 64 bit:

1. Make sure 32 bit image is same version as 64 bit version.
2. Install the 64 bit.
Linux Console credentials: device42/adm!nd42
Web console credentials: admin/adm!nd42
appliance manager credentials: d42admin/default
3. Do a backup from 32 bit image and check "Meta data backup" while doing the backup.
4. Do a restore on 64 bit image.
5. Make sure to change your IP/DNS settings on 64 image and shutdown the 32 bit image(because you might have 2 machines running scheduled jobs).
6. Optional: Base 64 image comes pre-configured with 4 GB of RAM and 2 vcpu. You can increase the memory and CPU as per your environment.
