The command "./dspace database migrate ignored" does not work, it gives an 
error. What do I need to do to migrate ONLY the Data (Database) from 6.3 to 
7.5?

We follow these steps (To migrate ONLY the old database to the new one):
* We did the PG_DUMP on the "dspace" ( Server   6.3) that has data and 
applied the PG_RESTORE from this base on the  Server  7.5 dspace (The 7.5 
Dspace was clean). Everything ran without error!
* When applying the command [Server 7.5] "./dspace database migrate 
ignored", it gives an error.
