After updating from 10.6 pimcore v to 11 version, facing version count issue

Question

I have updated pimcore 10.6 v to pimcore 11, followed all the steps as per pimcore documentation.

i executed 2 commands. In the version command getting below error attached

command => php pimcore10.6_migrate_o_prefixes_versions.php

Exception {#1022
   #message: "Call to undefined method seto_versionCount in class Pimcore\Model\DataObject\Tier"
#code: 0

./pimcore10.6_migrate_o_prefixes_versions.php:26 {
› $data = null;
› $data = $version->getData();
›
}
}
}

actually this version command is there for migrating versions from 10.6v to 11.0, in my case while executing causing above error.

can anyone let me know how to solve this?
