"Keep original positions" or not for templates in jUpgrade? - Joomla! Forum - community, help and support

going through jupgrade joomla 1.5.26 2.5 , i'm setting parameters , got selection of

"keep original positions"
yes or no?

what , should set as?

(i tried migrate joomla 2.5 2 months ago , no articles show in template on other page except home page... going through again see i've done wrong.)

thank in advance.

i think has template's module positions. in j2.5 used new naming convention module positions position-1,2,3 , on.
are upgrading template ?
in case don't think setting has fact see articles on home page.
and see on rest of website ?
