Upgrading keys to larger than 1024

[AdamC]

I have keys that I have used (sparingly) since 2004. This is a 1024
keysize. That keypair has a few signatures through key signing.

What is the best approach to upgrading keys to 4096? Is it just create a
new keypair and then go to lots of key signing events again (pain), or is
there a way to do this with my current keys?

TIA
Adam
