I only found a conversation from 2005 which didn't end with a solution - maybe there is one in the meantime???
I made a backup of the old server, put this on the new one, reinitialized the database on the new, made a "successful" restore of the DB - BUT start WCS failed with these messages:
ERROR: ld.so: object 'libblas.so.3' from LD_PRELOAD cannot be preloaded: ignored.
Cannot run with the current schema. Exiting.
Apache server is already stopped.
Failed to start WCS server.
Is there a way to to this?
