Move from IT audit into IT advisory

I was just promoted into a senior IT auditor within a big4 firm during this year. I worked 2 years in The Netherlands, and 2 years in UK. My main role has been as IT auditor in large companies in the corporative sector. I have knowledge in SAP, Oracle, AI and Blockchain, I moreover have a masters in management of technology; but I want to move to management consulting, more specifically in IT advisory. I would like to know a second opinion to reach such change, and requirements before getting the position if possible. Thanks in advance for any good advise, this will be well received.
