[lubuntu-users] On Lubuntu 18.04, is a 32-bit /home compatible with a 64-bit home?

Thank you very much for commenting on my proposed change, based on your 
extensive experience.

A hard-drive that is on its 'last-legs' is driving me to change now.

I think what I'm going to do, since I still need to support both 32-bit 
and 64-bit asound library Java-native code, is that I will start with 
restoring to a 32-bit system on the new drive, then try what I mentioned 
above, restoring to a 64-bit system.

At some point, when I am satisfied with the 64-bit system, I will 
'transfer my flag' to the 64-bit system.

I'm assuming that since Lubuntu 18.04 is a Long Term Support system, and 
that it now supports 32-bit architecture, that it will continue to 
support 32-bit architecture through its support life.
