After that forest and domain function level will raised to the windows server 2019. once FSMO role migration completed, Domain controller running windows server 2012 R2 will be decommissioned. A new domain controller with Windows server 2019 will be introduce and it will be the new FSMO role holder for the domain. Domain and forest functional level currently operating at Windows server 2012 R2. In here, the FSMO role holder is running windows server 2012 R2.
