Upgrading Fisheye and crucible

[Venug Pampati]

I have fisheye and crucible version 3.0 and would like to upgrade both to latest version 4.6. I have understood that the update process does not perform an in-place upgrade, but installs the new version of Fisheye.

Fisheye and Crucible used to a be a separate software. However as of Fisheye/Crucible 2.0, they become one. Any versions of Fisheye or Crucible from version 1.6.6 that would like to upgrade to the latest version must go though this process otherwise user information will be lost due to table changes between older versions as compared to the latest. 

So In my case since i have Fisheye and crucible version 3.0 i can go for latest version of both 4.6. Since they become one form version 2.0, now the i question have

1.Do i still need to install both fisheye and crucible in order to upgrade? or

2. Can install either one of them if so how to do connect both products?

Thanks in advance
