I have created blogs for S4HANA 1610 and now 1610 FPS1 is released with minor changes in sequence and note numbers.
Can I copy the 1610 blog and make changes where needed ? This would save lot of time in creating fresh blog
A quick Google search reveals that this is possible in WordPress with import/export option and with some plugins.
From what I can see, none of these is available to regular users here, so your best option would be just to go to edit mode of the existing blog, CTRL+A, go to the tab of the new blog and press CTRL+V. You will need to copy-paste the title separately and add the tags, but, normally, this won't take you more than a few seconds.
I suggest you modify your existing blog. As FPS01 is release this will become the go to release for all and I am sure nobody would start now with 1610. Similarly in May ppl would start directly with FPS02 once its released.
