"I have to mirgrate it".

You can of course learn Moose well from tutorials and cookbooks and slides as presented in other nodes,but also find out what are the benefits they are seeking from the migration and what is the timeframe they have. That will give you very good idea what you shoold look for. See which resources they can provide for the same, if they are familiar.

Important thing is to start writing test for your existing code and make sure that it doesn't break with the new code. Start small with Moose and pave your way further.

You can take help form online communities as well as IRC Channel #moose.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
