Registration users might be interested in changing the security from one setting to another in their registration database. Although it is recommended to choose a particular security setting at the time of starting to use the application and stick with it during subsequent upgrades to newer versions, it might be necessary to change the security setting at a later time. In such situations, users will find the following guidelines useful.

• From No Security to Single Cardinality -- No
  

See ChemicalRegistation_Upgrade_to_Security.pdf document for details about the issues that could be arise from this change in security setting.

• From No Security to Multiple Cardinality -- Yes.

Mapping of lots to concepts will not change by this security change.

• From Single Cardinality to Multiple Cardinality -- No

This change to Multiple Cardinality schema will have the same problems of going from Single Cardinality to No Security setting.

• From Single Cardinality to No Security -- No

Removing security from a single cardinality system is unlikely to work OK.

• From Multiple Cardinality to No Security -- Yes.

Associations of lots to concepts will remain correct when this security setting is removed.

Registration users may contact BIOVIA Support if they need any further more details about the security change that they are considering in their registration databases.
