We have done migration from Teamsite server 6.1 SP1 Solaris 8 to Teamsite 6.7.1 Solaris 10.We have manually set the branches permission to 771 using chmod as the branch permissions were not properly set by iwaccessmigrate. After migration in new server we found all the branches are visible to all our users .We have setttings branch_security=true workarea_security=true in iw.cfg and still the branches are visible.
