Add another DC to Hybrid configuration.

There is one DC, one on-prem Exchange 2019, Hybrid configuration. I need to add another one DC. Just adding a controller is no problem. The hybrid configuration raises concerns. What needs to be done on the Exchange server? I mean, for example:

Set-ExchangeServer -Identity EXCH01 -StaticDomainControllers DC-01.dc.com,DC-02.dc.com

Set-ExchangeServer -Identity EXCH01 -StaticGlobalCatalogs DC-01.dc.com,DC-02.dc.com

Thanks.

    Unless you have already statically set the DC, ( which wouldnt make sense with only one DC initially) then you do not have to do anything here. Exchange wull use both DCs just fine as long as they both pass the suitability tests.

    You can verify by checking event 2080 on the Exchange Server app log
