Migrate to v1.7 from v1.6 but without loosing current theme!

[Ashish Sharawat]

Hi,

Can someone help me to keep my current modified default-bootstrap theme from v1.6 and migrate my store to new v1.7 without any error? 

I try to export my theme and upload it to new v1.7 but it shows not for this version! 

And when I migrate my store using 1-click migration by unselecting the update theme option it shows 500 Server error! I try to fix it by removing default-bootstrap theme folder from the theme directory and replace it with classic theme! Now my backend is accessible but all got messy please check that in attachment!

@Ashish Sharawat No offense, but your question seems to indicate that you are not familiar with Prestashop. You are an ambassador for a shop software that you do not know. That desn't make sense. The different architecture of 1.7 i nothing new, it was discussed in this forum and the Prestashop blog e.g. for years.
