Sparky

Given the task I have given Sparky framework to cope with, it has worked remarkably well. However I need to improve the performance and wish to purchase a mobile template that I can migrate the current layout to.

Most functions are working well on mobile (m.winnr.net), but it isn't quite there in terms of overall presentation and performance.

I therefore seek advice as to which template to purchase.

Check Hot Reponsive and Hot Reponsive Porfollio

I'll give the Hot Reponsive Porfolio a try.
Probably a daft question, but do you do the migration from Sparky prior to any configuration or do you go through the detailed set-up process first?

Can you reformulate your question?

OK, you download and install the new Portfolio template. What do you do next:
a. Follow the configuration procedure of Portfolio
b. Migrate the Sparky template

Actually best you do hot_start to get same site as on our demo, then just change content
