If one currently has multiple wallets could they all be moved to one Coldcard without sending onchain transactions?
looks like atomic wallet was compromised - used by millions of people around the world - not the first and will not be the last popular wallet to be compromised
if you are saving significant amounts of bitcoin consider upgrading your setup to coldcard + sparrow wallet - it is an accessible, powerful, and incredibly secure setup - in the future you can use the same setup to easily upgrade to multisig

Discussion
you can import the seed of one of the wallets then wipe it and then import a different one - not ideal for two main reasons: (1) you have to keep wiping and entering seeds (2) if you do not generate a fresh seed on the coldcard offline then you could still be vulnerable to issues with the previous wallet you used
best to create a new seed following the above guide directly using the coldcard and transferring bitcoin to it as onchain transactions
