A client of mine asked “.. will change the hard disk on the ERP server, so she is worried how [they] can check that the data is transferred correctly to the new disk?”
My response was:
—
I’m not sure if the ERP Server HD’s are Raid/SAN or any platform. My comments are as follows;
- Strongly caution “Precisely everything has to be the same” — some programs/sw checks on HW indentity, be very careful
- Strongly recommend of doing a full clone of the HD instead of coping/moving
- A complete run through test with the user to check if the functions of the application are as normal as prior to change.
- A change management document from various related party of the change to for later audition.

Nowadays, with storage technologies like SAN/RAIDS, it seems that ordinary HD swaping is completely out of normal operations.
A friend of mine had a very bad experience when he was informed that the Data were completely backed up – running to find out later that the backed up data couldn’t be restore because they were stored on the same hard drive!
