While starting a new delta pass, you are hitting the error message “Unable to run a delta pass. Your first successful pass is more than 3 months old”.

Licenses have no expiration date. Once you have purchased a license, you can use it whenever you want.
However, once you have succesfully migrated a user, a drive, a group or a site (it means that the migration went in status “Completed”), you cannot run a new delta pass more than 3 months after the migration was completed.

How to proceed if you’re reaching this 3 month limit

The limit is per license. It means that one of your users may be impacted, while the limit for another one started later may not be reached yet.
If you are reaching this limit, you may contact Cloudiway support that will allow you up to 2 additional delta passes during 1 week:

• 1 delta pass before your cutover
• the final delta pass that will run quickly as there will be almost nothing to migrate

The platform is a migration engine, not a synchronization engine.
If you want to be able to run more delta passes over the incoming weeks, you will need to purchase new licenses and contact Cloudiway support to assign these new licenses to your users.

Important Note

Cloudiway is storing metadata to avoid to duplicate items during delta passes.
In particular, it stores the id of the Item to migrate and the date of last modification.

As per GDPR regulation, customer data are stored during 3 months. If there is no activity on your project during more than 90 days, data will be automatically deleted.
It means that if you start your migration and interrupt it during 6 months and come back to complete the migration (even if you purchase new license), you will endup with duplication of items since your metadata would have been deleled.
