For BEx Workbook Conversion you need to be at least SAP NW BW 7.01 SP11.
For use of Workspaces: BW7.30 and BWA or HANA
And here an interesting quote from product management in following document:

"Recommendation: use BW7.0 EHP1 or SAP NetWeaver BW 7.1 as there are significant TCO and integration improvements between BusinessObjects Enterprise and NetWeaver"
Best regards,
Victor
