Thanks Carel  

The requirement for LSB is for Reporting purpose and it is initially been created as Physical standby as the Primary Hardware was not stable as well as Database size is too big to be backed up on the Disk. Now we have got all issue resolved and so thought of taking this database back to the LSB  

Thanks Again for your views and suggestion Sanjay

Conversion between Standby types is non-existent. You have to drop the PSB, and re-instantiate an LSB.
I don't know whether you are right or not, LSB is released with 9iR2, and certainly isn't very stable.
I wouldn't rely on it for HA-purposes. For reporting, with restrictions in mind about unsupported data- and objecttypes, the cost of additional logging etcetera, it might help you.
Don't jump into solutions, but get your requirements for standby written down properly first. Then determine whether a proposed solution will work. And test!
You might consider (if space allows you) to have PSB as well as LSB. PSB for HA, LSB for reporting.

Regards, Carel-Jan
