It depends on what you mean by "master node". If you mean the "accumulo-master" service in 1.10, it should just be a matter of killing the service on one node, and starting it on the replacement node. If you have other processes/services on the same node that you need to migrate, you may need to address they may require special care. To make the transition smooth, you could pause anything that would create a FaTE operation, such as creating/deleting/cloning tables, user compactions, bulk imports, creating/deleting namespaces, merging tablets, or import/exporting tables. You can use the shell's "fate print" command to see if there are any outstanding operations.
