Commercial license
Commercial licenses for Structure (Server) have no expiration date, while commercial licenses for Structure (Data Center) do expire. When a Data Center license expires, Structure is accessible in read-only mode.
Both types of commercial license have maintenance expiration dates. You can only use a license with versions of Structure released before this date. To use newer versions, must purchase a maintenance renewal to extend the maintenance expiration date by one year.
Evaluation license
Evaluation and temporary licenses have an expiration date. After that date, Structure is accessible in read-only mode.
Make sure you renew your evaluation or get another license key before the expiration date.
Read-only mode
If the current license is invalid—for example, it’s expired or you upgraded to a version of Structure not covered by the license's maintenance date—Structure is only accessible in read-only mode.
In read-only mode, users can view structures but they can’t edit or manage structures until an admin installs a valid license.
