One single .odt document.
Some pages are portrait, others landscape orientation.
At the moment two page ranges: 1st with portrait, 2nd in landscape.
Pages need to be reordered, means pages, landscape one to move to document front.

In future, when document gets more logical parts, maybe further reordering will be needed.

A TextDocument in Writer has no pages in the sense of individual objects. It can be divided into any number of sequences (may include ordinary manual breaks) for wrapping and numbering pages. Each such sequence then has a PageStyle associated with it. To create a new sequence one must insert a manual break with explicit selection of the next PageStyle. (Later the PageStyle assigned to the sequence can be changed by a DoubleClick in the ‘Stylist’. And two adjacent sequences can have assigned the same PageStyle without being merged.)
What one may wish as “moving a page” must therefore be done in two steps:

  1. creating or freeing a page sequence and assigning the desired PageStyle.
  2. copying or moving the text content.
    I don’t know a method to move the PageStyle in one go with the text. If this is needed frequently for a special reason, I guess you have to write UserCode.
