Working on outdated technologies is definitely a career risk.
Look out in the market about the current trending technologies and which ones are more related to the work you do, your organization does, or you are interested in. Get trained on those technologies. Self-learning is very critical but doesn’t rely just on that, get formal training. Do some sample projects and build a portfolio.
Talk within your company if they can move you to another project using contemporary technologies (which you learned), cite your dedication and the long time spent with your last project. Also, your training will show the initiative. If a lateral movement can happen within the organization, that would be the safest bet.
Otherwise, you can start applying for jobs demanding new technologies.
