Hi,

 

before upgrading to 4.0.x i had all tables set to InnoDB engine. After upgrading, i am seeing that some tables are MyISAM:

ibf_core_message_posts

ibf_core_message_topics

ibf_core_search_index

ibf_nexus_packages

ibf_nexus_support_replies

ibf_randmsgs

Is it safe to convert them to InnoDB or they are MyISAM because it's better for those tables?

Regards

ibf_core_message_posts
ibf_core_message_topics

in my database these tables are not MyISAM but InnoDB

MyISAM makes sense on some log-tables and can speed up the system.

only MyISAM Tables:

core_javascript
core_theme_settings_fields
core_follow
chat_log_archive
cms_pages
core_tags
