When I attempt to migrate a project from ISE 10 to ISE Design Suite 11.1, Project Navigator does not consider an applied Design Strategy in the following two cases:
1. I have a Design Strategy applied and that strategy file can no longer be found.
This can occur if a Xilinx strategy no longer exists (for example, it has been removed from the Xilinx install), or a user strategy has been moved or deleted.
2. I have a Design Strategy applied and that strategy file still exists, but the contents of it (property values) have been changed.
Strategy options and settings might be changed from release to release in order to best fit the strategy goal for that release.
If a Design Strategy is not found during migration, the strategy will not be applied.
However, process properties that have been set in the design should be correctly applied.
