On the windows operating systems there isn't any problem doing this as long as the new account has the right permissions granted.
You need to take several things into account (are you using trusted connections to databases etc)
Thank you so much for your response.!!
I have installed Informatica 10.2.2 H1 on Linux servers but not on Windows servers.
We are not using any trusted connections to the database also.
Kindly provide your inputs what will happen if we start the Informatica services with a different user account other than the user account used for the installation.
Awaiting for your reply and Thank you in advance.!!
If both accounts have identical permissions granted the application should start as usual.
There shouldn't be any problem.
Thank you so much for your quick response and appreciate it.
