Cannot upgrade from 6.1.10 to 7.0.10

[stefan123]

Hello guys, I need some help.
While I am doing upgrade from 6.1.10 to 7.0.10 I am constantly getting this error 𝘌𝘳𝘳𝘰𝘳 𝘰𝘤𝘤𝘶𝘳𝘳𝘦𝘥 𝘸𝘩𝘪𝘭𝘦 𝘌𝘴𝘱𝘰𝘊𝘙𝘔 𝘳𝘦𝘣𝘶𝘪𝘭𝘥...
These are errors from the log file:

• Index for table 'email' is corrupt
• Key column 'ics_event_uid' doesn't exist in table
• Key column 'created_event_id' doesn't exist in table

I don't know where these columns belong, database is enormous and I don't know what can I change because I have over 200 000 accounts.

It looks like you should convert MyISAM engine to InnoDB: https://www.espocrm.com/blog/convert...ine-to-innodb/

Don't forget to make a backup before converting: https://docs.espocrm.com/administrat...p-and-restore/
