Data access after Project Online (PWA) retirement

As the retirement of Project Online (PWA) approaches, some questions have come up regarding what will happen to the data and related content.

I’d like to ask if anyone has information or guidance on the following points:

• What happens to the data currently stored in Project Online after the retirement date?
• Will this data still be available for viewing, export, or migration after that date? If so, for how long?
• Regarding the SharePoint sites linked to PWA, will they remain available? Will it still be possible to access or modify their content?
• Does Microsoft plan to publish official guidance on this transition?

Any references or practical experiences on this topic would be greatly appreciated.
