Can I upgrade to the GlassFish Message Queue 4.4 version for free if I have a previous version of the GlassFish Message Queue product?
Customers who purchased prior versions of GlassFish Message Queue and also have a current maintenance contract for these products are entitled to a free upgrade. Sun customers should use their normal support channels to request the upgrade. All corporate customers with Sun Software Support contracts should be automatically notified of the upgrade via the Online Support Center.

Customers of previous versions of the free Platform Editions or customers without a current maintenance contract on this product cannot upgrade for free.
