Redoing VMware vCenter server wiith new database

We have vCenter 5.5 running on rather old physical hardware with SQL 2008 database remotely located.
I have installed a new vCenter 5.5 running on a VM with local SQL 2012 server.
Rather than transferring the old database, I am thinking of creating a new database.
I know that I will lose the performance data, and will not have HA and DRS for 15-30 minutes while old server is down and new is not fully configured. (I have no Distributed vSwitches.)

Is there any other downside?
What precautions do I need to take? Thanks.

other than your Inventory View missing and Customization Specifications, and other items, you have sited.

There are no downsides really, it can all be quickly re-created from scratch with 30-60 minutes.

Make sure you Remove the Hosts from existing vCenter Server, before adding to new vCenter Server.

VMs will remain up.

HA will remain active, as vCenter just provides the means to configure HA!

It's just no DRS or vMotion!

In my initial attempt, I had tried to add host servers to new vCenter without removing them from old vCenter (that machine was shutdown) and a message was shown that this will remove the hosts from previous vCenter. I could click OK or Cancel. I clicked Cancel but is there anything wrong in doing it this way? In other words, not removing hosts from old vCenter till new vCenter is ready to grab them? Thanks.
