I need to merge 4 Jira Software Cloud instances into a fight on. The instances that need to be migrated have next gen projects type.
Wich migration method do you suggest me if I need to keep the sprints?
Thanks

Cloud does not have this option available yet.  You will need to follow the documentation here in order to do it.  https://confluence.atlassian.com/jirakb/merge-multiple-instances-of-jira-cloud-779160767.html

Hi! Thanks for your answer, I've read that document but I thought that maybe it could be another method that it wasn't there. 
If those are all that exists I will try the one that suits my needs.
Thanks again.
