Hi,

we are migrating our SharePoint 2007 environment to 2013. to do this, we have one SharePoint 2010 interim environment.

migration from 2007 to 2010 worked well and there were some issue related to customization. and those were fixed.

Now from 2010 to 2013, its giving issue. we are doing database migration. the server 2010 environment has sql server 2008 r2 and SharePoint 2013 environment has sql server 2012.

after restore the database from the sql server 2008 database back up, and running the power shell command

Mount-SPContentDatabase - Name -webapplication Url.

below error is thrown. 

Mount-SPContentDatabase : Content database data integrity check has
encountered a severe issue that upgrade process must be stopped. See the
upgrade log for more information about how to resolve this issue.

You can see that you have issues that you must resolve manually in your content database, mainly:

• The list 'AllEFormDepositary' at URL '/HR/PerformanceAppraisal/AllEFormDepositary' has a schema that is incompatible with this version of SharePoint.
• The list 'ArchiveForReports' has more than the limit of 262 fields of type 'Single line of text', 'Choice', or 'Hyperlink or Picture'.

You must resolve these by backing them up, deleting them, doing the upgrade, and then putting them back afterwards.
