Upload projects from version 25.6 to 25.10

[yanabrovar]

Hello!
We attempted to migrate our projects from version 25.6 to 25.10, but we've encountered an issue. The upload process takes an infinite amount of time and does not complete. Additionally, if the page is refreshed during uploading process, all model elements are lost, leaving only the tree structure intact.
Kind regards,
Yana

Hello,

Thank you for using SysON.
Did you follow the migration process from the official documentation? (https://doc.mbse-syson.org/syson/v2025.10.0/installation-guide/migration-process.html)
If so, do you have a stack trace to share? (from the server and/or the browser)

Regards,
