End of Sales (EOS)
The date that signifies when a specific software or appliance release will no longer be available for purchase.
For the majority of Citrix products which incorporate a date based license model, the EOS date is generally not applicable since new connection licenses work with previous product versions. In the event that a product line under a date based license model is being brought through End of Life (EOL), there will be a minimum 90 days notice of the EOS date.
Citrix products that have been added to the portfolio via an acquisition, or have yet to transition to the date based license model, will typically offer a licensing method that associates connection licenses to the product version. In these cases, there will also be a minimum of 90 days notice of the EOS date.
The 90-day notice period gives customers the opportunity to purchase additional licenses to allow for growth while they plan for a version upgrade or deployment of a new release.
