Shell Scripting , need to search and replace a string in AIX

Hi Guys,

I need to search and replace a string in AIX using variables and should be case insensitive.

I am able to search and replace using below command but its not working as case insensitive.

Code:
cat abc.txt | sed -e 's/$a/$b/g'  >  abc.txt

But i need to perform this with case insensitive , it should ignore upper/lower case.

I have tried below code but its working only in Linux , not in AIX , any help??

Code:
cat abc.txt | sed -e 's/$a/$b/gI'  >  abc.txt


===============================

Example :- I have a variable value called "hello" in $a

Below the the file abc.txt.
Code:
HELLO , My name is mohit.

Now i need to search for $a i.e "hello" in abc.txt and replace it with another variable say $2 , whose value is "hi"

Sample O/P
Code:
hi , My name is mohit.
