moving system database and log files

Is it ok to move master, model and msdb database and log files from C drive to D drive, to free up 10 GB space on C drive? Do I need to take any precautions, other then having a verified backup?

I used the steps copied below for moving some user databases files and logs, but I am not sure if I will be able to move master database and log files using the procedure below after I run the first step of taking master offline? Do you suggest any other way? 

1. offline the database.

alter database db_name set offline;

3. modify file path
use master;
Go

alter database dbname 
modify file (
    name = 'logicalName', 
filename = 'D:\new\db_name.mdf'); --> This is the new file location 

alter database db_name set online;
Thanks in advance.
