The client had a 15 year old legacy Sco Unix system, and asked ITVET to replace the existing server hardware, and upgrade to the latest version of Sco. The Sco system operated the whole company’s operations, from accounts to manufacturing, which included the operation of the actual plant and machinery. Prior to contacting ITVET, it had been identified by the owners that the legacy hardware was failing, and that there were no valid backups, which left them vulnerable to a complete shutdown. As there were around 100 employees, this was unthinkable. The project was made more difficult, as some of the existing infrastructure was so old, that it had become redundant, with support no longer offered by the manufacturer.
After consulting with the client, and carefully assessing the situation, in the first instance we sent engineers to site, who managed to access the systems and take extensive backups, of both the system state and data. We then built new servers off-site, which were installed with the latest version of Sco, and the data and system state uploaded, so they could be tested in a “non-live” environment. Once it was established that the servers worked correctly using the client data, the project went ahead.
Our engineers installed the new servers on site, and then set about the task of testing connectivity to the legacy infrastructure. This was no mean feat, especially with no support available from the makers, and working with 20 year old equipment! However, testing was successful and after a few dry runs, the client was able to shutdown the old legacy servers for the last time, and start using the new “much faster” servers. This was achieved with zero downtime to the plant, much to a very relieved client! Apart from being very appreciative, the client informed us that the speed of the new servers meant that tasks which used to take 45 minutes to complete, were taking less than three minutes.
