Old Aperture vault
I have some old aperture vaults which I have used to archive my photos when I was using Aperture around 2012 etc
Now Aperture is long gone, and I dont use it anymore, how do I re-open a vault and move it to say photos or Lightroom ? Is an aperture vault a fully built set of files ? Is hope it is not relying on anything referenced a
I want to be cautious because if I try something which is not proven, I am worried I may ruin the vault and loose all those photos I have kept safely on backup drives... but now I'm not sure what software to use to get back to them,
Thanks
