Is there a chart available on the Broadcom Support Portal with information on XCOM Data Transport version end of support dates?
End of Service (EOS), End of Life (EOL), Stabilization Dates and other dates are available by viewing the chart on the XCOM Data Transport product home page.
You will need to scroll down the page until you encounter the "Product Lifecycle Details" section. Use the Search icon to "Search by Description", for example "Windows", to narrow down the list of platforms and versions.
