SharePoint Upgrades from 2007 and 2010 to 2016

Hi,

Just to clarify an upgrade procedure.

There are two separate environments hosting SharePoint for the company:

1. SharePoint 2007 with 2003 SQL Express

2. SharePoint 2010 with SQL 2008 R2

Currently, there database is roughly 20GBs and wants to migrate both environments to SharePoint 2016 and not 2013.

There are hardly any customization done to the environments except for minor workflows. However, for the second 2010 environment documents are named in a particular order.

To quickly summarize my approach I would say and please advise me otherwise if wrong:

1. Migrate the SP 2007 with SQL 2003 Express to the SharePoint 2010 with SQL 2008 R2 (or will it be to SQL 2005 first?) through a database attach upgrade

2. Then migrate the 2010 environment that now has the SP 2007 data to a newly created SP 2013 environment again through database attached upgrade.

3. Migrate the SP 2013 environment to the newly configured SP 2016 environment?

Is it ok to export the SQL data from the 2003 Express and SQL 2008 R2 to a brand new installation of 2014 SQL for SharePoint instead of the above steps from one version consecutively to the next of SharePoint or third party tools to upgrade?

Haven't migrated any SharePoint platforms previously so any suggestions will be appreciated.

Many thanks,

ASLR
