Informatica 7.1:How to upgrade INFA from 7.1 to 8.1

We are to upgrade our INFA from 7.1 to 8.1.

We have chalked out the strategey as follows:

1/
At first we need to back up of our repository by using backup command in pmrep which syntax:

backup
-o #output file name#
-f (overwrite existing output file)
-d #description#
[-b (skip workflow/session logs)]
[-j (skip deploy group history)]
[-q (skip MX data)]

2/
Then to copy the old repository into the new location without copying the content.

3/
Install upgraded version client and server.

4/
From Administration Console create and select Repository Service.
Be alert for database type,cennection info and codepage-->Do not create repository content-->Create
Check all if u are sure-->Enable-->Actions-->Upgrade Contents.
Check for the contents once again.
