I installed 7.0.1 into a subdirectory of my webhosting account and used the data migration tool to transfer the data from 6.1.6 to 7.0.1 and lost 6 member's data in 6.1.6. While the information transferred to 7.0.1 and is in 7.0.1. It is no longer in 6.1.6. The idea was to transfer the information so that I can work with 7.0.1 in the back ground and make the modifications that I needed to make before I make the site live. To some people this may not be a problem since I am going to the new version 7.0.1 but this is a problem when 6.1.6 is still operating as the main website till 7.0.1 is actually released with the modifications I have added. Thankfully I did a back up of the database before I did the data Migration and I can restore the data with only loosing one person's information completely. I am giving a heads up on this because this can be a disaster if you are transferring a bigger database dealing with paying customers.
i cant imagine what did happen, but there is no logic in a record being removed from the existing database, unless there was something corrupt about the see more
It would be good to prove / disprove this.
Whilst I have found that there is much of D6 that is not transferred over to D7, I did not experience any issues with the primary database myself. Much though I like to have a pop at Boonex regarding the abysmal migration tools, it would surprise me if this if it is actually true.
