Absolutely!
In fact, you have to have coexistence in order to migrate from 2013 to 2019
You can use this guide to walk through it:
Exchange 2013 and Exchange 2019 coexistence in the same domain?

Hi,
Is it possible to have an Exchange server 2019 on a Windows server 2019 while already having an Exchange 2013 on a Windows server 2012 r2 in the same domain?
All mailboxes are migrated to O365 and the plan is to decommission Exch. 2013 and Only keep Exch 2019 for management purposes as Microsoft recommends.
After Exch. 2019 is operational and can be used to manage AD attriubutes, Exchange 2013 will be uninstalled.
My question is: is this feasible this way?
All answers are greatly appreciated,
Exchange | Exchange Server | Management
Exchange | Hybrid management

It went good. Except that we were unable to uninstall Exch. 2013 due to a corrupt database, but 2019 works fine.
