[xubuntu-users] Upgrading from 32bit to 64bit

[Peter Flynn]

A rather odd request. I have a Dell Optiplex 745 which I rescued from
oblivion last year when an office was being cleared out. I hurriedly
installed Xubuntu 16.04 on it and it's been fine.

It now turns out that I used a USB containing the 32bit distribution
instead of the 64bit, so I wanted to know if there is a way to "upgrade"
in place from 32bit 16.04 to 64bit 16.04

The 745 runs a 64bit processor and architecture, from what I have been
able to determine (at least, it boots from the 64bit ISO on a USB stick,
and everything seems to run OK).

Or do I have to do a from-scratch installation (not a major problem, as
/home is on a separate partition, and most all the important stuff is on
SVN repos).

Hi,

of course you *can* do that. Here's a guide for Debian based systems: 
http://users.digitalkingdom.org/~rlpowell/hobbies/debian_arch_up/index.html

But - and that's a huge 'but'! - you should ask yourself if it's worth the 
time, headache and hassle when a simple reinstall is doable much easier.

Regards,
vinz.

I concur. Unless there is a compelling reason to keep the current
configuration a rebuild is the path of least resistance here.  If the data
is an issue either pull it out to an external drive or gpart a partition
for the migration where you can tuck the data you want to save. If it is
just a challenge you want to take then, well, lets have some fun.

You would be better off reinstalling your system using a 64bit distro.
There has been talk about a successful upgrade from a 32bit core to a 64bit
one. Yet that procedure is not fail-proof and might require you to compile
your own kernel.

Debian has a procedure for this particular activity. I suggest, set aside a
24hour day to preform these steps. https://wiki.debian.org/Migrate32To64Bit.
Yet this is a debian procedure designed for debian systems. I still
wouldn't try it.


You be better off backing up any critical files you have (docs, scripts,
config files) and reinstalling a 64bit distro

I did exactly that. As I keep a separate backup of additional
non-standard stuff, it worked just fine.

For the record: Recommended:

1. If you can, create a /home partition, or install a second drive
   and make it /home (or whatever structure you want for the place
   where you keep *your* stuff).

2. If you have non-standard stuff you have added, *always* keep it
   somewhere like /usr/local/src and back that up separately (eg
   to USB), or rsync it to some place else.

   I also keep things like the installation tar.gz files of the
   small amount of commercial software that I have bought in that
   directory too, so I can reinstall it from there if I need to.

3. I have a bunch of shared stuff that I use on lots of systems,
   mainly my Emacs add-ons and my DTD/Schema collection, both of
   which have standard locations in /usr/local, so they are in
   SVN repos on my server, so I can add them back to any newly-
   installed system without difficulty.

I'll pass on that, thanks :-)

Works fine. Better, in fact, as the ltXML2 utilities were giving me
problems compiling them under the 32bit distro, but under 64bit they
compiled and installed without a glitch. Some C++ weirdness.

[Daniel Wastak]

Backup ~/home/{account name}
Do a fresh install of Xubuntu 64bit
Restore the home account.
You will still need to install any apps you may have installed
on the 32bit version.

This is the safest and easiest way to do this.

You can use "Synaptic" to export the list of all installed packages,
before you do the new install. After the installation you can import
this list and all your software is back.

Re: [xubuntu-users] Upgrading from 32bit to 64bit use Aptik Migration Utility

The EASIEST way to do install a new system from existing is to use Aptik
Migration Utility.
