We have upgraded our ECC from ehp 5 to ehp7 and installed a new portal 7.31.
I have applied custom theme in portal which is working fine.
But this theme does not apply to WDA(Standard like ESS, MSS and custom) as after upgrade ECC is using sap corbu theme so background color is grey and font is also very different.
We tried changing the stylesheet(downloading ie6 file and changing it and again uploading it) at ECC side but we were getting many dump. So reverted it.
Please let me know whow can we make the look and feel of WDA same as portal theme.
