I have one server with disk partitionned. One partition is running ubuntu server 16.04 with lxd 2.0. I just installed on second partition ubuntu 18.04 with lxd 3.0.3.
I would like to move my containers from present server to new one.
Of course, both servers can’t run at the same time. If needed I can access files of the other partition however.
I tried the procedure given by Stéphane Graber here Backup the container and install it on another server
But when I tried to run lxc launch bck-container newcontainer I have this error :
Error: Requested architecture isn’t supported by this host
On a newly created container lxd3 , I can see its architecture is “i686” whereas in lxd2 container, it is “x86_64”.
Is it possible to do what I want ? How to proceed ?
