iServer Windows migration best practice guide
enclosed is the default migration guide for the iServer. This is pretty much the steps that we will use in the migration process :
TOPIC : iServer Hardware Upgrade Checklist -- Migrating iServer to a New System
https://support.tridia.com/admin/viewfaq.php?faq_id=266 OR FAQ #266
TOPIC: iServer certificate preservation.
The most important thing to remember ( and I'll also update Ahmed on this very same issue ).
Is that by upgrading the iServer ( which I assume you will be installing a NEW server, please confirm this point .... )
1- New certificates will be generated for the iServer. That is the SSL/TLS , PKI will generate
a new 'self-signed' digital certificate.
2- Your EXISTING iAgent user base is working with the CURRENT ( that is your current iServer's certificate ). You want to use copy over the OLD iServer's certficates to the NEW iServer. We have detailed steps on how to do this in the FAQ.
3- Now since you are migrating over the weekend remember that the current iAgents are CONNECTED to the OLD iServer you will want for them to disconnect and then reconnect to the NEW iServer. The best technique here is using DNS. Each iServer should have the same DNS Name, but of course different IP's. You would first just DOWN or just un-plug the host machine running the OLD iServer, This will force a disconnect of all the iAgents and will place them in re-try connect mode. You bring up the new iServer with the same DNS, but differen IP ( yes, you could use the same IP again ... ), but what this does is to allow the iAgents to connect to the new iServer.
TOPIC : iServer Windows Optimization
Just a couple of details. Please make sure that you followed these steps below to optimize the new iServer:
From faq : https://support.tridia.com/faq/showfaq.php?faq_id=209
Configuring Windows 2012, 2008 and 2003 Server for iServer high connection count usage (best practices)
There are several steps that you can take to insure the maximum scalability of the iTivity iServer when running on your Windows Server. Please consider applying these updates on your iServer if you plan on having more than 200 iAgents and iManagers connected simultaneously.
Optimize Performance of Background Processes on Windows 2012
For the best performance of the iServer services, please set the system to optimize background processes.
[Start] -- [Control Panel] -- [System and Security] -- [System] -- [Advanced system settings]
System Properties -- [Advanced] -- [Performance] -- [Settings]
Performance Options -- [Advanced] -- [Processor Scheduling] -- [Background Services]
Performance Options -- [Visual Effects] -- [Adjust for best performance]
Also to set the ephemeral port limits on the iserver ...
TOPIC: iServer port optimization under WINDOW
Optimize Ports and Connections on Windows 2012 and 2008 Server
In order to provide the greatest level of scalability for the iServer running on Windows 2008, Tridia recommends expanding the available dynamic or "ephemeral" ports and reserving a range of ports that is highly used for explicit binds by the iServer. Please consider applying these networking updates on your iServer if you plan on having more than 200 iAgents and iManagers connected simultaneously.
netsh int ipv4 set dynamicport tcp start=7000 num=55000
TOPIC: Make sure the iServer is set to auto-start after the system reboots
And just in case ... let's make sure the iServer will start automatically when the system is rebooted :
Choosing Start > All Programs > iTivity > iServer > Administrative Tools opens a menu with additional options.
Select the option to 'Configure Automatic iServer Start'
184.108.40.206 CONFIGURE AUTOMATIC ITIVITY ISERVER START
Choose this option to set up the iServer to start automatically each time the system starts.
TOPIC: License new iServer
2.4.1 Obtaining the License Key and Activation Key
When you purchase your license, Tridia provides a license key. The license key is a series of numbers with hyphens:
When you install the iServer, the install process generates an install code. This install code is displayed on the License Status dialog (see Section 2.4.4, below).
To activate your iServer, you use the install code to obtain an activation key. The activation key is generated based on the install code and is unique to your iServer system.
To obtain your activation key:
1. After installing the iServer, choose Start > All Programs > iTivity > iTivity iServer > Tridia Licensing > License Information to display the License information dialog. Note the install code.
2. Contact Tridia with the install code to obtain your activation key, or visit the Tridia Support Site at https://support.tridia.com/ and choose the Licensing option.
After obtaining both the license key and activation key, you can proceed with licensing the iServer.
