The concept of milestones in Clarizen is slightly different than in MSP, which is why they usually do not carry over (Milestones in Clarizen contain the tasks required to achieve them). After importing the project, you can change tasks to milestones by selecting one or more items, then going to Misc >> Change Type in the Menu. Also if you need to create new objects into your plan, if you use Insert (as opposed to Add) it will create the new item above what you have selected. As for critical status, is this a custom field? The MSP priority field does get pushed into Clarizen. Thanks!
