    String or binary data would be truncated when Upgrading Umbraco

    Using Umbraco And Getting Started
    Umbraco 8

    Hi I'm trying to upgrade Umbraco from 7.15.7 to 8.18.3 (as a experiment at this point) and I'm running into the "String or binary data would be truncated" error when doing so. I think I traced it to the cmsPropertyData table's dataNvarchar column being renamed to varcharValue and it's data type changed NVARCHAR(512). I base that on reading the log file.

    Is it possible to keep the data type of NVARCHAR(max) on that column during the upgrade? I have about 100 entries in that column over 512 characters long.

    Any help is appreciated and thanks,

    Drew

    Unfortunately I never found a solution. I did write a quick script to copy off the too long data into a new table then shorten it. This allowed the installation to continue. The script I used is:

    select * into cmsPropertyData_bak from cmsPropertyData
where len(dataNvarchar) > 500

update cmsPropertyData
set dataNvarchar = LEFT(dataNvarchar, 500)
where len(dataNvarchar) > 500
