Merge two accounts in AD with one account in azure AD

Question

Hi,

I would like to know how can you merge the attributes of 2 accounts on two different domains in AD onpremises with one account in azure AD. Actually there are few accounts in our enviroment that works like that, but we don't know how to do that with new accounts. In the screenshot we took from the Metaverse Object, you can see that the first attribute "accountEnabled" is given from the account in the first domain, the attribute accountName is given from the account in the second domain and the cloudanchor is the one that the cloud assign.

We tried with soft-match and Hard-Match without luck on new accounts which have the same upn, editing the properties proxyaddresses, etc.

We ran out if ideas, so I would like to know if anyone has tried this scenario and how can we merge the properties.

Thanks beforehand for any information
