And if it is indeed possible, how can I switch from i386 to amd64?  Can this be done with the apt tools?  Then during the migrating some packages will be from amd64 already while others will be still i386. How does that go right?

Celeron 440 for sure is 64-bit. Pentium 4 2.00 GHz I am not sure, there are many models and variations of this processor. Is it socket LGA775 also?

family 15 model 2 is northwood based. no amd64. the best option for that one is to find a cheap second hand box with a CPU that's only 10 years old instead of (literally) 20 years old and retire it; those old p4's were really power hungry, and it shouldn't be hard to find a replacement for a cost (maybe even free) that will pay for itself in electricity savings alone.
