Can you promote multiple DCs at once?

Hello,
I was wondering if we can run DCPROMO script simultaneously to bring 8 DCs into 2003 environment without waiting for each DC to finish with replication. Or maybe the other option would be to install them with the option to have critical updates replicated and reboot and then install next one....? There is a switch for that for the script.

WE are running the following script to install DC and according to the script, it receives the replication before reboot....it takes more than one hour. Could we run the script to promote other DCs at the same time? Please advise. The DCs would be only additional DCs for the domain.

THank you.

Below is the script:
install-ADDSDomainController -InstallDNS -DomainName "lab.com" -DatabasePath "E:\NTDS" -SysvolPath "F:\SYSVOL" -LogPath "F:\Logs" -ReplicationSourceDC "2012R2.testlab.com" -SiteName "Default-First-Site-Name"

as one of the best practices, it is highly recommended to promote DCs one bye one, better in a sequence ordered by site, link speed and number of working clients.

doing them at the same time may cause conflicts and other sync issues.

DCs are critical servers and far less than the clients, you normally don't do anything against them in rush. :)
