If they are already have same version and they can be stacable. ( you need downtime and shuffle stack cables and second stack required re-numbering)
1. Power down the second stack, re-number the device with priority
2. Rack the new switch in same cabinet
3. connect switch 5 and 6 with stack cable, switch 1 at a time.
how to connect cable and re-number refer below guide :

Dear balaji
1) After Power down second stack .. shall i renumber switch 1 renumber 5 , switch 2 renumber 6.wr mem then connect with first switch stack then switch ON both switch one by one ? . I can see all switches have same priority 1.
this is enough ?
OR before connecting switch 5 & switch 6 first need to renumber active switch priority from 1 to 15?. Please suggest . Thanks

- that should work
- make sure your master and slave switch have high priority so other can not become master, since master and salve (best practice connected uplinks).

- changing priorty always good idea and rebooting stack (will get this effects only, so take maintenance and do it?)
