Does W2K3 SP2 need to be installed to both Domain Controllers in the same night?

We have one domain with two Domain Controllers. Both W2K3 Standard, No service pack installed, the schema had been updated to R2. Both run DHCP and DNS services.

FSMO Roles are:
DC1: Schema Owner, Domain Role Owner
DC2: PDC Role, RID Pool Manager, Infrastructure Owner

I'm hesitant to upgrade both DC's to SP2 in the same night. Can we upgrade the second DC a few weeks after upgrading the first? Are there any known issues or caveats in doing it this way?

Thanks,
mokn

Yes you can.   However, aren't you actually on SP1 (if you're on R2)?

No, we are not on SP1. We had to 'extend the schema' a while back for another project that required it. We used the adprep tools to do so. So now we will be going from no Service Pack, to Service Pack 2.

Interesting...however, you can update one at a time without any trouble.

Upgrade to SP2 went well. One DC is on W2K3 SP2 and the other has no SP. It's been about a week and I haven't found any issues. I will be installing SP2 to the other DC next week.

Thanks,
