Restore a Bucket backup from 4.5 to 4.6

Couchbase Server
1

Hello,
I’ve backup a bucket on 4.5 using this command:

cbbackup http://localhost:8091 -u Administrator -p xxx -b HR /home/student/backup

I’ve compress and transferred the files generated using this command:

tar -zcvf archive.tar.gz 2017-05-03T142037Z to the target system (4.6).
And then run the restore:
cbrestore /home/student/backup/2017-05-03T142037Z/2017-05-03T142037Z-full http://localhost:8091 -u Administrator -p xxxxx --bucket-source=HR --bucket-destination=HR -v -vvv

However the restore operation is not done:
cbrestore /home/student/backup/2017-05-03T142037Z/2017-05-03T142037Z-full http://localhost:8091 -u Administrator -p xxxxx --bucket -source=HR --bucket-destination=HR
student@ubuntu:~$ ./restore_hr
.
bucket: HR, msgs transferred…
: total | last | per sec
byte : 0 | 0 | 0.0
done

This is the output with verbose :

how about add rehash=1

cbrestore /home/student/backup/2017-05-03T142037Z/2017-05-03T142037Z-full http://localhost:8091 -u Administrator -p xxxxx --bucket-source=HR --bucket-destination=HR rehash=1 -v -vvv

Hello,
In 4.6 is necesary to use -x rehash=1

And work fine.
I’ve load the HR bucket.

Thanks for the help.
