Disadvantages

The disadvantages of migrating trusted storage with data preservation include the following. (See Pre-Migration Tasks for details.)

This type of migration requires an online connection between the back office and the LLS to allow synchronization from the back office.
The migration works only with FlexNet Operations Cloud as the back office. It does not work with FlexNet Operations On-Premises.
Modifications to the SA configuration are required to enable synchronization—either online or offline—to the back office if one or the other is not already enabled.
Modifications to the LLS configuration are required both to enable a new timestamp-compatibility policy for synchronization and to enable synchronization from the back office if it is not already enabled.
