<p>I'm looking at maybe moving from an older AMD64 to a new Intel dual-core which is 32 bit. Installation isn't a problem but can I transfer all the installed apps? I haven't been
able to find anything so far on Google except where the migration is to a similar platform and file-system. I won't change the filesystem but the platform will be different. Is there something on the lines of the "World" file in Gentoo?</p>

For everything you've used apt-get to install, if you want to create a record of what's installed run the following:
```
```
dpkg -l|awk '/^ii\s*(.*)\s*/ {print $2}'|packages.txt
```
```
This will create a text file with all the packages you have installed.  Then after you do the install, create and run a script with the following:
```
```
#!/bin/sh
for p in $(cat packages.txt); do apt-get install $p; done
```
```
Notes:
1) Since you're moving from 64 bit to 32 bit, some of the packages might not be compatible.  I would grep packages.txt for '64' before running the script above and find alternatives if they are needed.
2) Anything you've installed from source, you'll have to make a note of and install from source again.
Good luck!
