I would agree - when we (at that time, de.teutonet) converted a few years ago,
this was an amazing overhead, having to go through all the small local NICs.

Unfortunately, a global search & replace for DNS related entries doesn't exist
;-)

The rest of the transition went rather smoothly - renumbering DNS records
themselves was a mere UPDATE statement for our database, and renumbering the
hosts themselves - while truely annoying and sometimes boring - was painless.

We went through this rather quickly, configuring both netblocks in parallel,
moving DNS, waiting for it to propagate + a little bit longer to be really
sure ;), and then turned of the old block.

The other major issue which crept up was having to reconfigure VPNs and
firewalls - but I don't see a practical way to solve this.
