<p>Through the work the Central Digital and Data Office (CDDO) is currently undertaking
we are seeking to develop an overview of the magnitude of the legacy estate initially
across ministerial departments.</p><p><strong> </strong></p><p>CDDO has established
a programme to support the Government remediating its legacy technology, resulting
in a new risk-based framework designed to assess legacy IT assets within government
departments. Through this legacy framework CDDO has collated a list of the highest
risk systems across ministerial departments and followed up on this to ensure that
they all have appropriate funding and remediation plans in place.</p><p><strong> </strong></p><p>CDDO
is building a community of practice across government for legacy remediation which
will enable the capture of lessons learnt and best practice for dissemination and
sharing cross-government to accelerate legacy remediation. This will enable CDDO to
create an overview of the magnitude of the legacy estate initially across Ministerial
Departments.</p><p><strong> </strong></p><p>The cost to the public purse of external
contractors used to maintain legacy IT estate cross-government is not centrally held.</p><p><strong>
</strong></p><p>The Government is unable to provide an estimate for the whole of government
in relation to the years specified, as this is a devolved matter for individual departments
and their Accounting Officers.</p><p> </p>
