This explains upgrading from SI4.6 to SIX.
There is no direct path from SI4.6 to SIX. SI4 data and Projects must first be converted to SI5.5 format, then they must be converted to SIX format.
Each Project must be converted individually.
You must contact Support in order to receive a temporary SI5.5 CD Key to proceed.
You will need to register SI5.5 with the temporary CD Key that we provide you.
The default location for your SI4 database is: C:\Program Files\D-Tools\SI4
See here for instructions on importing Projects. Although you can convert Sales Orders and Work Orders to SI5.5 format, these will not convert to SIX format.
When you convert SI4 Projects to SI5.5 format, no Revisions will be converted.
