There is always information which does not come across completely. For example, report setups and awards/recognition reminder criteria in VolunteerWorks are not compatible with VSys One.
Reports. Nothing about your existing VolunteerWorks reports imported into VSys One - their layout, design and basic underlying principles are completely incompatible. VSys one has over one hundred and fifty built-in reports and letters of its own, which include just about anything you had in older programs, and which you can customize to include additional data as you need it.
Mandates. Mandates in VolunteerWorks are simply sets of textual notes rather than explicit criteria, so their raw contents are brought into VSys One as a custom field, and can be manually made into VSys One mandates from there.
Jobs. VSys brings all of your jobs and departments in from VolunteerWorks, and all of your volunteer assignments and job associations. The jobs themselves come through as empty shells with just their names. You'll have to re-enter the properties of those jobs (requirements, contact information, etc.).
Awards. VSys knows who got what awards, the award type and when, but not the criteria for the nominations of awards, so you'll have to set those up just once for each award type.
