How to merge 2 gcp project

Question

我有2个不同的gpc项目，一个包含所有正在运行的服务器，另一个运行我的firebase应用程序是否可以合并这2个？

Answer 1

At present there is no GCP options to merge projects, however I have created a feature request to provide this functionality in the future. There is not ETA but any progress on it can be followed at the above link.
As a workaround you can create VM disk snapshots images of your VM instances from one project and move them incrementally to the other. Once you are completely sure that the migrated VMs are working properly in the destination project, you can shut down the other project which you can still restore within 30 days in case you may need to do so.

I am not familiar with Firebase so you would have to take into account any issues with DNS resolution and domain issues with your application if you decide to move the app in that project instead.
