Dear Zextras Support,

We have been using Zextras Software suite since 21 April 2015 ,500 numbers of perpetual license. Now we want top shift that license to a new Zimbra 8.8.15_GA_4018.FOSS email server from our old server 8.8.11_GA_3772 FOSS.The version we are suing in Zimbra 8.8.15_GA_4018.FOSS is 2.12.2.
Now I dowloaded the zextras using link wget and when I try to install it its throwing an error as follows.

root@email:/home/mailadmin/zextras_suite# ./ all


Checking for existing installations ...

FOUND Zimbra 8.8.15 FOSS P22

Error: Could not find or load main class com.zextras.ZxSuite
Caused by: java.lang.ClassNotFoundException: com.zextras.ZxSuite

Unable to determine the minimum required ZAL version

Exiting ...

Hence please help me to install the zextras in my new server
