I switched my ignition Data server to new machine and migrated all the data from MYSQL database to the new server. But , when I am trying to access this historian through Ignition Trend , it is not fetching the data from database, Where I can see only current historian data.
After data importing to new server, is there anything else to be done in order to view those old data through ignition Chart mode/Historical trend mode.?
I can see the data tables are copied into new server through MYSQL workbench, but not able to fetch those through SCADA trend. Any idea what could be wrong?
History migration is a complicated subject, fraught with potential problems. Your best bet is contacting support so someone can troubleshoot ‘live’ - the number of possible problems could take weeks to work out via forum.
