So today I updated all the extras apart from MIGX
Next I ran the update from 2.4.0 to 2.5.0 and encountered the 'could not open upgrademodx log issue so I proceeded to open this log file in MODX manager, then edit and save it, then I proceeded with the update from 2.4.0 to 2.5.0.
This worked but I was unable to log into MODX manager. After a bit of Googling I found it was due to the 'createdon field in the modx_users table' that occasionally does not update when upgrade to 2.5.0.
I found Bob Ray's solution which got me back into MODX manager:

Next I proceeded to update to 2.6.0 then to 2.6.5 all ok front end and back end.
I did find some issues in the log file at core/cache/ install.config:

Ignoring these I proceeded to update MIGX FROM 2.6.8 TO 2.12.0
I did have this following error in the MIGX install log:
Error adding index category to migxConfig: Array ( [0] => 42000 [1] => 1072 [2] => Key column 'category' doesn't exist in table )
However, Lo and behold my MIGX tables were found again in MODX manager link to MIGX
The only difference I could see was I no longer has the CMP link in the top menu.
I have done some front end testing with forms, members and storing data to database and everything seems to be working ok. Am I correct in assuming those files that were not found or installed that showed up in the core/cache/ install.config are not so important?
Or do I still have to fix these?
Either way, a big thank you to Bob Ray for his super helpful advice and great website that lists so many MODX solutions
