Hi All, I'm using the migration tool to migrate between community editions 1.9.2.3 to 2.3.5-p1.
I migrated the settings successfully with no errors.
On the data migration step, just after the inventory step completes, I get:
[2020-09-08 18:49:04][INFO][mode: data][stage: integrity check][step: Inventory Step]: started 100% [============================] Remaining Time: < 1 sec [NOTICE]: You can use --auto or -a option to ignore not mapped differences between source and destination to continue migration In Data.php line 97: Integrity Check failed
Checking var/migration.log, there is no more information. It just shows the inventory step started as the last line.
There is one error, much earlier, because I am using Amasty's percent shipping plugin on 1.x and that plugin is not available for Magento 2 (I will need to start fresh with shipping.) But it did not seem to stop on that error, just kept going until it dropped after the inventory step.
My question is, is it safe to use the -a option to ignore mapped differences, or is there a way to look further into seeing what it has a problem with.
here is the complete output of the log file:

I went ahead and used the -a option and it completed the data migration step successfully with no further errors. There was only a warning for the percent shipping method not being available which was expected. No errors.
Hopefully didn't botch anything up...
