[Koha] zebra utility after koha upgrade

[George Mikuchadze]

After successful upgrading koha from v3.22.21 to v19.05.17 zebra indexer
doesn't work in the crontab.
I have the following cronjobs:
PERL5LIB=/usr/share/koha/lib
*/5 * * * * KOHA_CONF=/etc/koha/koha-conf.xml
/usr/share/koha/bin/migration_tools/rebuild_zebra.pl -b -a -z >/dev
but after 5 minutes od adding new biblioitems they are not searched.
If I run the command in the shell:
$ KOHA_CONF=/etc/koha/koha-conf.xml /usr/share/koha/bin/migration_tools/
rebuild_zebra.pl -b -a -z >/dev
the new biblioitems are appearing in serch results.
Can anybody help me to set up a crontab for the zebra rebuild utility?
