Old VS New Data

[Weld3z]

Good day..
What if I got a new device with new SD installed with around two months' worth of data?
Is it safe to simply install it and import the new data to merge them with the old? I don't want to lose my old data on Oscar it's been since 2015 

Or shall open a different profile and keep them separate?

Thank you,

Is the new CPAP from the same manufacturer as the older one? If not, then a separate profile needs to be used.

No, it's not old was Phillips new is Resmed.
Was hoping to keep all my Data in the Profile but that's fine.

Thank you,
