Compile with Delphi 10.3

[Andsup]

I'm moving a project from delphi 2007 to delphi 10.3.

I had to rename the TRestClient class to TfcRestClient. Not a big deal.

Still some error during the compilation: Incompatibility between Tdataset and TclientDataSet in datasetconverter by example

How to deal with those errors ? Is using cast a valid option ?

Thanks for your support
