1. Yes. However, please consider this information from me as strictly preliminary, and await the official announcement to finalize the code changes. If you are a .NET SDK developer, please await the release of the official updated version of .NET SDK to start the migration.
2. As Eikon Excel is a product and not an API, we would not be the best source to advise you. I would expect that if you have followed the PCN, you have the changes covered. If there will be any additional actions required, Eikon/Refinitiv Workspace product team will issue official guidance, and your Refinitiv account team keep you informed.
On Refinitiv Tick History:
Please find Refinitiv Tick History - Mandatory Technical Migrations about the upcoming changes.
More detailed guidance for developers, including step-by-step migration advice on Refinitiv Tick History, is planned to be made available next week.
On Eikon Excel:
Please find Eikon Excel rebranding detailed under PCN 11803, as the changes will apply to Eikon Excel product.
