    “We have utilised Xynomix consultancy for multiple projects. Most recently we have enlisted their consultants help to complete an Oracle database migration to new servers. As part of this Xynomix used their specialist knowledge to set up an appropriate backup and data retention policy in line with industry best practice. The work was, as always, completed in a timely, efficient manner.”
