How to increase main memory for one master node in the cluster?

Explorer

Hi i have 3 node cluster(1 master and 2 worker nodes) on aws platform with m3.large instance i.e 7.5 memory and 2 cores. now in my master i have name node in that certain amount of metadata.

now i am planning to increase memory and cores to m4.2xlarge on master node.

if i change instance type to m4.2xlarge directly from aws does my name node memory lost?

To change the instance type please suggest me good practices?

Thanks in Advance.
