In theory - you could live without the FSMO roles for a while - quite a substantial time in many cases, however if you are planning downtime it would make sense to transfer the FSMO roles.<br />

Do bear in mind that the other DC should also have DNS and Global Catalog installed and DHCP also assuming you use that. All clients also need to have the second DCs IP listed as either the preferred or alternate DNS server (or have these supplied via DHCP).
