Issue publishing Skype for Business 2019 topology

Need help in Implementing Skype for Business 2019.

I am in the process of Implementing Skype for Business 2019 in our company. We already have 2015 Skype for Business with 2 different pools as we have 2 sites(but in the same domain). However, one issue I currently have is that the CMS(Central Management Server) is still hosted on a Legacy Database(SQL 2008), it wasn't moved to the latest database back then. So, until the CMS is not moved to the compatible Server(which is minimum of 2012), the topology for 2019 will not publish as it keeps saying that there are legacy systems and the topology is unsupported .

I wanted to ask if I could create a new CMS with the already existing(old) CMS and parallelly run the new SFB 2109 Deployment? Or any other ideas if you people can help me with?

Thanks
