I want to upgrade moodle database from 1.9.4 to 2.6 . But due to large database it is looping during quiz upgrading.
I have done below steps for upgrading
1) upgrading from Moodle 1.9.4 to 1.9.19
--> Upgraded sucessfully
2) upgrading from Moodle 1.9.19 to 2.2.11
3) I need updated 2.2.11 to update 2.6 but not able to update till 2.2.11 yet
---> Looping forever in mdl_quiz upgradation due to too many quiz attempts in our database
Two table mdl_question_states(5.6gb) and mdl_question session (2.5gb) is too big to be upgraded and it is looping forever with execution related to these table during moodle upgradation.
I want to know the process to upgrade database (10.8 gb ) only with moodle 2.6 compatibility.
