convertDomain error - from rpas 13.3.0 to 13.4.0

 Hi,I am getting this error when I try to convert an mfp domain from RPAS 13.3.0 to 13.4. I am using this to upgrade my 13.3.0 mfp domain to 13.4.0.

The 'src' domain is a global domain with 4 local domains - ldom0, ldom1, ldom2, ldom3. I specified only the global domain path in -dest domain.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

onvertDomain caught Exception: Schema version 2 != 10, Value type double != string for Btree '/u01/e95038/planning/home13/RPAS13/mfpretail/domain/mfprtl/store.db/store_props.ary'. in line 2083 of file '../../../Libraries/preIIbtree/BPlusTree/preIIrpas/PageManager.cpp'

convertDomain exited with status: 4

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Also, is convertDomain necessary, is upgradeDomain enough to convert/upgrade domain fromm 13.3.0 to 13.4.0?
