Hi,

I am applying for Visa 176 from Queensland under ICT Business Analyst. As per
 
it requires ”
5 years specialising in C++/C#/C, Oracle, PeopleSoft, SAP or SIEBEL, completed in last 5 years, evidenced in statement of service”.

I have more than 6 years of experience and already have three experience letters from my old employers which consists of job description based on the Business Analyst role but doesn't particularly highlight the technologies in experience letter.

Will I need to re-take all experience letters with this change (I know it will take much time) OR can I just take 3 reference/recommendation letters (having technology area as well) from my three ex-managers and then submit with company experience letters?

Will this way work for State Sponsor?

Thanks in advance.
