Upgrading a trial to a license?

I have about 30 days left on my 60 day trial, and I just purchased a 16gb license.

We are using 17.5tb of storage, so I am planning on buying an additional +2tb license.

It looks like I have to install the 16tb license, before I can get a real serial number, and purchase the +2tb license.

So, during that period, I will only have a 16tb license, even though I have 17.5tb of data.

This server is being used for production. Is it necessary to take down the server to apply the licenses?

Thanks,
Rob

Unfortunately, applying a license does require a reboot..

As you already have 17.5Tb of storage , and they are in use , then you have to put the 2 license ( the 16Tb and the other 2 Tb ) ,because if you put the 16 only ,then the DSS will not work , so you have to put the 2Tb,
in this time ( the time you need to put the 2 license) it’s the stop time or let say the time that DSS will not respond to you .tell you put the second key .

i recommend if you can tell other people to stop sending data for few minutes tell you can put the serials.
