You can order upgrade/downgrade from online store client area: go to “my products”, then “product detail”. Available options for upgrade/downgrade will show up there. However, if you have an existing pending invoice, you have to pay the invoice first then you'll see the upgrade/downgrade options.
Your license will be updated from our license server automatically once invoice is paid. Your local license key will be auto-updated within one day. If you want it to become effective immediately, Please run following commands to retrieve a new license key,
/usr/local/lsws/bin/lshttpd -r /usr/local/lsws/bin/lswsctrl restart
assuming LSWS is installed to /usr/local/lsws.
You can check number of lshttpd processes running to verify the effective license. For 1-CPU and VPS, there will be two lshttpd processes running, for 2-CPU, three lshttpd processes, for 4-CPU, five lshttpd process, for 8-CPU, 9 lshttpd processes.
If you have any issues, please create a ticket with license department from client area.
