I am using the RB750Gr2 for now nearly 7 years and the thought has crossed my mind what do I do when this hits the dust. No doubt it will keep going because it has been such a great device but I am planning to have a another similar Mikrotik device ready with my current config loaded as a back up should my router eventually fail. The question I have is do I buy the RB750Gr3 or wait for a refresh. Are there any plans to release a new MIPS based device to refresh the RB750? If I got with the RB750Gr3, then is it as simple as exporting my settings into script file from Gr2 and importing it into the Gr3?
