Open Source Document Management

I tried to upgrade to 7.3 but I failed so far. I think there are some SQL commands missing in the upgrading script.
First I do not see any additional attribute of any document, also any thumbnail. After I opened an issue (s. http://issues.logicaldoc.com/ticket/599)

For example, following commands were missing. But I'm sure, there are more:

alter table ld_document add column ld_pages int not null default -1;
alter table ld_version add column ld_pages int not null default -1;

Because after that, I've got new error messages... A little bit disappointing...

Somebody, who can help?

Dear , if you ahve a valid Customer Number please communicate with the support team at support@logicaldoc.com

I'm using the Community Edition, so I don't have any customer number.
But I solved the problem by myself. I compared the tables after migration tool with that created by LD itself. Then I removed the default values (look into my post above) and now everything works fine.
