Hi I followed all the instructions in [this link](https://meta.discourse.org/t/migrate-a-mybb-forum-to-discourse/130789) but when I ran the migration script, the following output appeared. I have a few questions: **1. Was the migration completed successfully 2. . If the report below indicates an issue, is there a way to determine the exact cause of problem?** **Beginning of the log** root@root:~/discourse$ bundle exec ruby script/import\_scripts/mybb.rb Loading existing groups… Loading existing users… Loading existing categories… Loading existing posts… Loading existing topics… creating users 875 / 1668 ( 52.5%) [454 items/min] Failed to create user id: 894, username: shahed, email: [sh-----@yahoo.com](mailto:sh-----@yahoo.com) user errors: [“Primary email has already been taken”] 1415 / 1668 ( 84.8%) [485 items/min] Failed to create user id: 1442, username: haqiqi.1410, email: [h-----@gmail.com](mailto:h-----@gmail.com) user errors: [“Primary email has already been taken”] **1576 / 1668 ( 94.5%) [497 items/min] Failed to create user id: 1603, username: 6530091424, email: [j-----@yahoo.com](mailto:j-----@yahoo.com)** **user errors: [“Primary email has already been taken”]** 97 / 97 (100.0%) [702 items/min] n] creating topics and posts 2481 / 11705 ( 21.2%) [620 items/min] Warning: probably incorrect quote in post 2659 7699 / 11705 ( 65.8%) [567 items/min] Warning: probably incorrect quote in post 8554 10133 / 11705 ( 86.6%) [583 items/min] Warning: probably incorrect quote in post 11160 **10323 / 11705 ( 88.2%) [583 items/min] Warning: probably incorrect quote in post 11584** **10548 / 11705 ( 90.1%) [582 items/min]** **private messages are not implemented** Creating redirects… Users… ``` 1660 / 1660 (100.0%) [7757 items/min] ``` Categories… ``` 101 / 101 (100.0%) [4056 items/min] ``` Topics… **Posts…** **3753 / 10652 ( 35.2%) [3111 items/min]** **banned users are not implemented** Updating topic status Updating bumped\_at on topics Updating last posted at on users Updating last seen at on users Updating first\_post\_created\_at… Updating user post\_count… Updating user topic\_count… Updating user digest\_attempted\_at… Updating topic users Updating post timings Updating featured topic users Updating featured topics in categories 101 / 101 (100.0%) [1875 items/min] n] Resetting topic counters **End of the log** **Thanks.** --- _[View the full topic](https://meta.discourse.org/t/error-in-migrating-a-mybb-to-discourse/347302)._
