Hello Ali Ashraf,
there ‘s <a href=”http://www.redbooks.ibm.com/abstracts/sg247777.html”>an IBM document </a>that describes the process from Exchange 2003 to Domino but I could’nt find anything about older versions; you could have a look at this and try it on a lab environment.
This <a href=”http://www.redbooks.ibm.com/Redbooks.nsf/RedbookAbstracts/sg246230.html?Open”>abstract </a>may also be of assistance.
If you can aford a third party product we used one from <a href=”http://www.binarytree.com”>Binary Tree</a>. It moved all the data, including public folders which were mapped to mail-in databases. This was several years ago so I hope their product still supports Exchange 5.5. the products are “CMT for Notes” and “CMT for Public Folders”.
