How to do a InsertOrUpdate with web services 2.0

Question

I understand that InsertOrUpdate method is just valid for Web Services 1.0.
a) Is there a way to do it with web services 2.0 ? I imagine using a query and then Update or Insert.
b) if we decide to use web services 1.0 would there be any cons ? (besides a possible performance issue as in the documentation)
c) InsertOrUpdate uses the record "user key" for identification. If need to identify using another field, I suppose that the only way is thru query, etc. Any other ideas ?
Txs. for any help.

Hello Antonio,
I understand that InsertOrUpdate method is just valid for Web Services 1.0.Correct, the InsertOrUpdate method is not available in WS v2.0.
a) Is there a way to do it with web services 2.0 ? I imagine using a query and then Update or Insert.That is one possibility, however it means that every insert or update would consist of two operations. I would suggest reviewing your requirements and expected use cases for a way to determine whether a record is being inserted or updated within CRMOD. The specific approach would depend on whether how the records to be entered into CRMOD are compiled (i.e. user interaction vs. batch sync component)
b) if we decide to use web services 1.0 would there be any cons ? (besides a possible performance issue as in the documentation)There are some objects that are not supported for WS v1.0 as well as the fact that field coverage is not as complete as the WS v2.0 interface.
c) InsertOrUpdate uses the record "user key" for identification. If need to identify using another field, I suppose that the only way is thru query, etc. Any other ideas ?Only certain fields or sets of fields can be used as a user key. These are described in the WS user guide. You can query on other fields to find a record in CRMOD but a unique value must be provided to identify a record for an update operation.
