Promote QNAP ADC to DC ?

[praneet]

Hi

I have a situation as follows:

- I had TVS-473 setup as DC which crashed and unfortunately do not have the DC backup.
- I also have TS-269pro setup as ADC for the above DC and is currently active and have backups for this.

Can I promote TS-269pro as DC? If yes then are there any steps/document I can follow?

I tried rebuilding TVS-473 as DC but it does not pickup DC settings and sets up as a new DC.

Is there any thing else I can do to bring back TVS-473 to its original DC state?

Would appreciate quick responses

Thanks
