I hope everything is good at your side
I can do your migration ,I have done several Unix and Linux migrations before
Just to give an accurate time I will need to gather some more requirements like MySQL data size, Current versions , and others
If you are interested I can share some commands with when executed will give clear estimate
Scope will be
1- copy and edit configuration files
2- backup and restore MySQL data
3- login to jumla and update paths
Thanks
