I'm trying to upgrade a large legacy TM (325843 units) in Studio 2011. The process takes a long time, but does finish without any error messages.

When the import was done, only 238506 units out of 325843 processed were "added". What happened to the other nearly 85000 units?

Thank you in advance for any advise!

When you upgrade a TM Studio will remove any TUs that it does not require. A TU is not imported if it is a duplicate of an existing one. Usually two TUs are equal if their source and target segments are equal. However, "equality" means they are also equal if they only differ in auto-substitutable placeables. Those, in turn, depend on the enabled recognizers.

For example, if number recognition is active, two TUs

(Give me 5 apples./Donne-moi 5 pommes.)


(Give me 6 apples./Donne-moi 6 pommes.)

are equal, even though their segments differ, and although my French is lousy. This is because the second can be created from the first by applying auto-substitution. One one will be imported and, if applicable, the custom field values of the other will be merged.

Similar processes exist for tags and formatting, measurements, variables, and date and time expressions.

There is an option when you upgrade to have all omitted TUs added to an xml file so you can see them afterwards and check why.
