SP2013 from migrated are missing webpart

Hi,

I'm migrate (Test zone) SP2007 > SP2010 no error any webpart.

And then i'm migrate SP2010 > SP2012, there are many missing webpart.

Example missing: 0b38cca7-0a5b-c334-66ea-1572d3d7f81a Type="Microsoft.SharePoint.Portal.WebControls.OWACalandarPart"

I'm query by SQL Server Management Studio tool with webpart ID 0b38cca7-0a5b-c334-66ea-1572d3d7f81a and found that it's in tp_ZoneID MiddlerightZone

OK, it's missing webpart ? i'm open that site in SP2010 and Edit page, go to Middle Right Zone, not found OWACalendarPart !!?

then i'm open same site in SP2013 and Edit page, go to Middle Right Zone, not found OWACalendarPart too.

When it's not found in SP2010 page why it's missing in SP2013 ?
