Hello,
From Talend 7.0 onward, a digital signature is added to each project item when it is saved in Talend Studio. When importing a project or project items, Talend Studio validates the signatures and rejects items with an invalid signature. This is a security measure to prevent accidental or malicious modification of project items.
However, you can import a project or project items exported from an earlier version of Talend Studio before the expiration date of a 90-day grace period from the first installation of Talend Studio or before the date set in the migration token, whichever comes later. Upon successful import, all imported items are signed.
Before setting a migration token, make sure you have received a migration token key provided by Talend upon your request.
Best regards
Sabrina
