Hi Amarnath,
You can upgrade your server from CF 9.0.1 to CF 9.0.2 however it only contains, the hotfixes and from this installation we have started support Solr.
About the vulnerabity we have released some security hotfixes ColdFusion 9 and 10 to fix it.
Easiest way to migrate or upgrade the server from CF 9.0.1 to CF 9.0.2.
First if your using CF 9.0.1 Enterprise edition, then create the car package which you can further deploy in ColdFusion 9.0.2
However if you're using CF 9.0.1 as Standard, then you have to follow the instruction.
Steps to follow :
NOTE : If you are using the ColdFusion 9 Standard version then follow the steps mentioned below else for ColdFusion 9 Enterprise version follow the steps under Build an Archive file.
As you are using the ColdFusion 9 Standard version, you need to first unserialize the Cold Fusion 9 to make the .car file that will contain all the settings of install Cold Fusion 9 running on Windows Server 2003
Close Cold Fusion 9 Admin Console.
Go to C:\ColdFusion9\lib and locate license.properties. Open this file in notepad or wordpad and then you will find the ColdFusion 9 Serial number there. Remove the serial number and save the file. Restart the ColdFusion 9 Application service.
Now open the Cold Fusion 9 Admin console.Then in the Cold Fusion 9 Settings summary, you will find that the ColdFusion Edition changed from Standard to Developer.
You can create the .car file from the ColdFusion 9 Developer edition.
Build an Archive File (.car)
In the ColdFusion 9 Admin Console, click on Packaging and Deployment and then ColdFusion Archives.
Enter the Archive name say Test and then click Create. You will get the same archive name now showing under the Current Archive Action List
Once you click Create, the Archive Window Information Window will pop up. If the same window did not pop up then kindly turn on the pop blocker.
In the left panel, click on Archive Wizard and then click on Select All.
Then click on Server Settings, Server Mappings, Data Sources and so on and you will find that all the Settings are checked.
NOTE : If you do not want any particular setting you can deselect that.
Once you are done then click on Close Window.
Click on Second Icon which say Build Archive (hover the mouse) under Actions in the
Current Archive Action List in front of the .car file name say Test. You will get the Archive Information Window.
Click Next and Broswe for the location where you want to create the .car file else you can create a test.txt on your desktop and rename the .txt to .car which means test.car.
Under the Choose Archive file location you can enter the path of the test.car file (C:\Users\username\Desktop\Test.car) and then click Next. You will get a pop up "Build Successfull.
So now you have successfully created a .car file say Test.car.
Also you can serialize ColdFusion 9. Open the Cold Fusion 9 Admin console in Windows Server 2003 and click on the “I” icon near logout (extreme top right corner).
Now go ahead and install ColdFusion 9.0.2.
Deploy the Archive file (.car)
After the install is complete then launch the Admin console of ColdFusion 10 and then click on Packaging and Deployment and then ColdFusion Archives
You can enter the URL of the .car file say C:\Users\username\Desktop\test.car and click Deploy under Deploy an Existing Archive or Browse to the location where you have placed the .car (test.car)
Click Deploy and you will get the Deploy Wizard Window.
NOTE : If the new Window does not pop up then turn on the pop up blocker.
Click Next in the Deploy Wizard Window and click Deploy. You will get a message Deploy Successfull. Then Click Close.
Restart the Service of ColdFusion 9.0.2 and you are good to go.
Hope this helps. Please let me know if you have any doubt,.
Thanks,
