[Vtigercrm-developers] 回复： Upgrade from 5.3

[sunny]

I think the my method is copy the tables directly from database,not take care of the data size.

Thanks for the helpful input Alan,


I've got no PBX integration so I'm clear on that count.


Is trawling this list archive the best way to get your improved script?

Do you test after each step or is the absence of errors a sufficient indication of success?


Kind regards,



Matt Bracewell

  Hi List,
 
 There has been much discussion here on upgrade scripts over the years
 and many examples of partial upgrades due to (silent) execution timeout etc.
 
 Is there any decent documentation on multi-version upgrades? Advice on
 best practice, ideas for testing, command line tools etc, etc etc.
  
 This is not straightforward.
 
 The web-based migration generally works for small databases and/or you will get an error when something goes wrong :-)
 
 However for bigger databases the web-based scripts suck. They almost always time out and die silently :-(
 
 When going from 5 to 6 you really need to "fix" the database beforehand to prevent the migration script trying to create and population the new crmentity label column - the migration code is incredibly slow and inefficient. (I have posted in here before an alternative script that reduced the time from >10 hours to a few minutes.)
 
 If you have PBXManager beware going from 6.1. to 6.2 - the script to migrate the PBXManager table doesn't really do anything as far as I can tell and again takes eons to do it... I have also commented on this in this list before.
 
 Documentation? Not that I have found.
 
 Best practice? One step at a time, keep your fingers and toes crossed, keep notes on what you do.
 
 HTH
 
 Al
