    initial v1  
    1010
    11111) Install the new cluster PostgreSQL 11 with new PostGIS 2.5
    12 2) you symlink the postgis-2.5 -> postgis-2.1 in new cluster
    13 3) Since you are running 2.1, you need to first drop the functions in your old cluster since the backing functions were removed in 2.2
     12
     132) you symlink the postgis-2.5 -> postgis-2.1 in new cluster - this is so when pg_upgrade goes looking for 2.1, it will find it.  It won't care it's 2.5 as long as the 2.5 has all the functions that it's SQL functions of 2.1 had.
     14
     153) Since you are running 2.1, you need to first drop the functions in your old cluster since the backing functions were removed in 2.2 and these present would cause pg_upgrade to fail.
