[root@localhost ~]# rpm -qa|grep Percona

Percona-Server-shared-56-5.6.17-rel66.0.el6.x86_64

Percona-Server-server-56-5.6.17-rel66.0.el6.x86_64

Percona-Server-client-56-5.6.17-rel66.0.el6.x86_64

[root@localhost ~]# yum -q downgrade Percona-Server-server-56-5.6.15-rel63.0.519.rhel6 Percona-Server-client-56-5.6.15-rel63.0.519.rhel6 Percona-Server-shared-56-5.6.15-rel63.0.519.rhel6

[root@localhost ~]# yum shell

[root@localhost ~]# yum -q update

To prevent that, we should lock our packages on current version. To achieve that, we need yum-plugin-versionlock package
which allows us to do this:

[root@localhost ~]# yum versionlock Percona-Server-server-56 Percona-Server-client-56 Percona-Server-shared-56

yum versionlock clear

[root@localhost ~]# yum -q versionlock list

[root@localhost ~]# yum versionlock delete '0:Percona-Server-client-56-5.6.15-rel63.0.519.rhel6.*'
