How to combine two json objects in powershell

Question

If i have two json files, how can I combine the objects using powershell? I would like the values in the second file to supersede the values from the first object. There is possibly nested complex objects within the json. Really I'm looking for a modern solution to ($Json1 ConvertFrom-Json) | Merge ($Json2 ConvertFrom-Json) | ConvertTo-Json as Merge is deprecated, and i cannot use that in my azure pipeline.

{
"name" : "value",
"type": "someType",
"color": "green",
"someComplexObject" : value of complex object
}

{
"name" : "value1",
"color": "blue",
"someComplexObject" : value of complex object
}

Where the final result would be

{
"name" : "value1",
"type": "someType",
"color": "blue",
"someComplexObject" : value of complex object
}

Should `$json2.someComplexObject` just overwrite `$json1.someComplexObject`, or do you need to merge them recursively? — Mathias R. Jessen, Apr 20 '20 at 20:55
If the properties were all different, you could use convertfrom-json -ashashtable, then add the hashtables. — js2010, Apr 20 '20 at 23:09

This solution does not merge 2 objects as described by the OP. It would create an array with both objects intact. – Brian Merrell Dec 15 '21 at 14:59
