Reinstall

general

I'm running Ubuntu 14.04.5 LTS with 64-bit kernel but 32-bit environment after originally installing version 12 as full 32-bit at some point I upgraded and ended up with this hybrid which runs fine but is now causing problems with installing rubygems as they think it's full 64-bit but then some 64-bit executables don't run. I don't fully understand but I thought the simplest thing for the future might be to do a clean install of 64-bit ubuntu (taking the opportunity to update to version 16.04) and reinstall all my apps to make sure everything is compatible.

If I fire up another Linode and install everything can I then swap my old IP address over to the new Linode?

I've got several web applications running and some websites that I don't control the DNS server for so switching IP at the DNS level would be a pain.

Am I mad? Is there an easier way?

Typically it is recommended that you do what you mentioned and completely upgrade to a 64-bit environment. The path you have chosen to take by creating a new Linode is also the safest as you can configure your environment beforehand to make sure everything works.

Yes, as long as both of your Linodes are in the same DC you can easily swap IP addresses.

Nope, seems like you've got the right idea :)

Thanks, that's reassuring that someone else agrees
