The import is therefore not possible in RZ10

After DBcopy, when I try to import the profiles parameters, I received this error

Default profile usr/sap/N25/SYS/profile/DEFAULT.PFL

Could not be read. The import is therefore not possible.

Instance profile /usr/sap/N25/SYS/profile/N25_DVEBMGS40_eccupj5

Could not be read. The import is therefore not possible.

Start profile /usr/sap/N25/SYS/profile/START_DVEBMGS40_eccupj5

Could not be read. The import is therefore not possible.

I need your help.

Thanks.

Vero.
