I would like to change the plan of Load balancer(NetScaler VPX). What do I need to pay attention to? Is there anything I should not do? What do I need to do to avoid any issue or error? Any precautions?
In DE1 and FR1 region, if you use "12.0-53.13 Standard Edition" or "older version" of the Load balancer(NetScaler VPX), please don't change the plan (e.g.: 50,200Mbps⇔1000, 3000Mbps).
If you should try to change the plan with the above-mentioned condition, the operation would be in error and then, you would not be able to do any operation on the Load balancer(NetScaler VPX).
To avoid any issue or error, you need to upgrade the Load balancer(NetScaler VPX) to the newest version, at first.
As for the upgrade procedure, please refer to the following URL.

After the upgrade, you can change the plan.
