WordPress MU

I'd like to put online an MU multiblog, and hosting it with HostGator.
I've just registered my domain with an italian provider, because HG can't register italian .it domains, and i wanted to transfer it after the registration.

I didn't know that domains can't be transfered before 60 days since their registration!

60 days are a long period and i'm trying to come out from this hook.
I'm thinking to register directly with HostGator a .com domain (example: myblog.com) and starting uploading and setting up MU.

I could configure dns for myblog.it, pointing to myblog.com

After the 60 days i would like to change in MU everything that links to the .com extension (email, links, etc...) moving to the .it extension.

In your opinion this could be a pain in the butt (think to subdomains for example), or there is a simpler way to coming out from this situation?

Thanx

Do you think you'll have any users? I'm thinking probably not. Unless you're already familiar with MU and have a plan all drawn up and know exactly what you're doing, getting the entire site launched in 60 days is a crunch.

That being said, you can change the domain name, but it involves backing up the entire database, modifying the domain name in every field it appears (do a search and replace on a COPY of the db backup ), the replacing the original db with the new copy.

Thanx Andrea for the info about backupping..yes, it seems a real pain! Now i'm taking information about a way to escape from this: maybe ccTld (cc is for country code) don't need the 60 days block period, it would be great.

For the other question: my MU site is ready, i should only put it online, and it has taken months of hard work to be done, cause it's my first time with Mu, php, sql etc...
