Hi @Michel Hubert ,
Thank you so much for pointing this out.
Please have a look at this page: https://aka.ms/tsi2rti > Readiness > TSI to ADX - Lessons
It contains the original TSI2ADX guidance, plus additional information how to migrate effectively, along with Fabric and tooling that facilitates the migration to either service.
The Accelerated Retirement Notice section contains additional information. The early retirement date is following recent directives from Microsoft's leadership, who emphasized prioritizing security above all else, including legacy systems support, our management team has decided to accelerate the retirement of the Time Series Insights service to July 7, 2024.
Furthermore, we will fix the docs page (https://aka.ms/tsi-to-fabric) by adding ADX as a second option. It shouldn't have been removed and we apologize in an already challenging spot.
