Fisheye - MySql 5.6 Migration From hsql Constraint Issue (Specified key was too long; max key length is 767 bytes)

When migrating from hsql to MySql 5.6 (pretty much fresh installation) I am getting an error which does not allow completion of migration. An exception is thrown when a constraint is applied to the following table:

{noformat} ERROR - Database migration failed: com.cenqua.crucible.hibernate.CruDBException: Problem with constraints script /opt/applications/fecru-2.10.1/sql/MYSQL/schema/constraints_80.sql

Hi Mahesh,

This is a bug that currently being tracked by our developer here: https://jira.atlassian.com/browse/FE-4507

If
this is a new MySQL instance, can you try downgrading to MySQL 5.5?

Cheers,
