Bitbucket server installation

[vinod kamble]

Hi Team , 

Currently  i am running bitbucket server on on-premise with  5.4.0 version & now i am  setting up new server on google cloud .

 but my question is .

1) Can i transfer my existing licence key to new server by degrading on premise licence .

2) should i use same 5.4.0 version setup on cloud env or i can setup newer version 5.12 using the same  5.4.0 licence key 

Pls help me on this .

Regards,

Vinod
