If you migrate to Amazon RDS from another database before upgrading to FlexDeploy 6.0.0.2, you will need to run an additional grant when you next upgrade FlexDeploy to 6.0.0.2 or later.
grant fd_admin to CURRENT_USER;
If you upgrade to 6.0.0.2 before migrating to Amazon RDS, this grant will already have been run.
Installing version 6.0.0.2 or later should work on Amazon RDS with no changes.
Prior to version 6.0.0.2, the grant
grant fd_admin to CURRENT_USER;
would need to be added after the fd_admin user is created.
