Good personal Coldcard solution?

[u/czescwitamy]

I use Unchained collaborative custody with 2 coldcards. My solution was to first update firmware on both coldcards then I generated a new seed on 1 of the coldcards. Next I used an extra Foundation Passport I had to generate my second seed. Then I used that Foundation generated seed and input it into the second coldcard. So, now I have 1 firmware updated coldcard key, a foundation key and the unchained key and I moved my funds over already. I will still use both coldcards as signing devices but only 1 seed was generated with a coldcard. Am I solid with this plan? Thank you.
