Migration Error: Call to a member function NumRows()

[joebordes]

Sorry, I don't know what I was thinking when I answered you.

coreBOS is the natural evolution of vtiger crm 5.4, so there is no migration script for a 5.4 database. One of the first things we did when we adopted the abandoned project was add coreBOS Updater

http://corebos.org/documentation/doku.php?id=en:devel:corebosupdater

Updater takes care of maintaining your database up to date with our code development. Once you are on coreBOS you can easily update your code from github and then load and apply the necessary database changes, you will never have to launch a migration script again.

The migration process that is in place is for versions lower than 5.4, to get them to 5.4.

So our goal for a vtiger CRM 5.4 database is to install coreBOS updater and have that extension take it from there.

You can read the details on this documentation page:

http://corebos.org/documentation/doku.php?id=en:upgradevt2cb

High level the idea is to setup a coreBOS copy with a copy of your database, install updater and apply the changes.

Give that a try and keep me informed.
