I'll answer my own post with an update for you dev people.

I got this to work by temporarily disabling DPL2 but I suspect this is a fairly common extension for people using SMW to have?

Upgrade seems to have workd and DPL2 is back on now.

I used SVN today to upgrade to the latest build and want to upgrade to the new store so I followed the instructions below:

(1) Login to your server, and change directory to [wikipath]/maintenance

This is a little misleading, should be [wikipath]/extensions/SemanticMediaWiki/maintainance

(2) Run php SMW_setup.php -b SMWSQLStore2 and follow its progress.

This worked OK

(3) Run php SMW_refreshData.php -tpv -b SMWSQLStore2 and follow its progress.

This failed until I added the following line (copied from setup.php):

set_include_path( get_include_path() . PATH_SEPARATOR .  dirname(__FILE__) . '/../../../' . 'maintenance' );

(4) Run php SMW_refreshData.php -v -b SMWSQLStore2 and follow its progress.

This failed and I've reached the limit of my debugging skills. I have no idea why DPL2 php files are involved in this! Error message is below:

[adv01@vps maintenance]$ php SMW_refreshData.php -v -b SMWSQLStore2
PHP Warning:  set_time_limit(): Cannot set time limit in safe mode in /var/www/vhosts/adv01.mysever.com/httpdocs/w/maintenance/commandLine.inc on line 238

Selected storage SMWSQLStore2 for update!
