-->It is the replacement of Visual Upgrade feature
-->Visual upgrade preserves old master pages, CSS and HTML files only where deferred site
collection upgrade preserves many things, even Features.
-->This upgrade allows you to use previous version of SharePoint UI seamlessly.

(SPWeb).
“Once the site collection is upgraded then it cannot be rolled back.”

SharePoint 2013 User Experience 


SP Mode 14
SP Mode 15

 SharePoint 2013 can host sites in both SharePoint 2010 Products and SharePoint 2013 modes. The installation for SharePoint 2013 contains both SharePoint 2010 Products and SharePoint 2013 versions of many elements. The directories on the file system are duplicated in both the 14 and 15 paths, for example:

    Web Server Extensions/14/TEMPLATE/Features

    Web Server Extensions/15/TEMPLATE/Features

There are also two versions of the IIS support directories: _Layouts, _Layouts/15 and _ControlTemplates, _ControlTemplates/15.

Be sure to install customizations to the correct location in your new farm. For example, additional style sheets for SharePoint 2010 Products should be installed in the /14 path, not the new /15 path so that site collections that you haven’t upgraded can use them. If you want a solution to be available to both paths, install it two times, and the second time use the CompatibilityLevel parameter when you install it, and it will be installed to the /15 path.

Reapply all customization:

During upgrade is that the new environment does not have customized features, solutions, or other elements. Make sure that all custom elements from the SharePoint 2010 Products environment are installed on your front-end web servers before you upgrade any content databases.
Manually transfer all customizations to your new farm. Make sure to install any components that your sites depend on to work correctly, such as the following:

    ->Custom site definitions
    ->Custom style sheets, such as cascading style sheets, and image
    ->Custom Web Parts
    ->Custom Web services
    ->Custom features and solutions
    ->Custom assemblies
    ->Web.config changes (such as security)
    Ensure that you transfer all unique settings from the Web.config files for each web application to the new servers.

->Administrator-approved form templates (.xsn files) and data connection files (.udcx files) for InfoPath. InfoPath is available in SharePoint Server 2010 only.
->Any other components or files on which your sites depend.

Verify the Upgrade Status:

After attaching a database, use the Upgrade Status page in Central Administration to check the status of upgrade on  databases. After the upgrade process is complete, review the upgrade log file to see whether upgrade produced issues, use a Windows PowerShell cmdlet to check the upgrade status for all the content databases.

Click here for more Information

Upgrade error log file and the upgrade log file are located at %COMMONPROGRAMFILES%\Microsoft Shared\web server extensions\15\LOGS. and also check the event logs.
The upgrade log file contains more detailed information than the upgrade error log.

The logs are text files named in the following format:

    Upgrade-YYYYMMDD-HHMMSS-SSS-error.log

    Upgrade-YYYYMMDD-HHMMSS-SSS.log

Where

    YYYYMMDD is the date

    HHMMSS-SSS is the time (hours in 24-hour clock format, minutes, seconds, and milliseconds)
