1
UK Link Technology Refresh
  • Annie Griffith
  • March 2008

2
UKLTR Cutover
  • Completed successfully ahead of schedule
  • Quicker than expected due to -
  • Less data needing final migration, enabling data
    to be transferred across network
  • Higher than expected speeds of data transfer
    across networks (75Mb vs. 45Mb)
  • No rectification activities being needed
  • Less time needed for batch catch-up
  • All business verification activities brought
    forward
  • First files released externally 1500 Monday 25th

Snags Issues
  • IAD Refresh had some minor problems and took
    longer than planned to bring completely in line
  • 47 shipper files were not transferred during
    re-pointing the file routing from National Grid
    data centre to UK Link data centre.
  • These were restored and processed successfully on
    29th Feb
  • Result of processing was identical to processing
    on Wednesday 27th
  • No knock-on impacts
  • Initial release of first files of each file type
    were slightly later than usual schedule, as all
    were pre-verified by xoserve prior to release.

Observations

    cycle, although most major invoice types hae now
    been issued successfully
