No, just remember to copy your important data out to somewhere else just in case before upsizing.
Alright, thanks. I think I sort of understand..
Anyway, Now I facing some network problem.
So I installed wordpress on my NAS, port forward and everything is working. When I access from external, I used my DDNS xxx.xx/wordpress , I can load but when I click any link within wordpress, it redirects my internal IP instead, 192.168.1.xx/whateverlink.
Any idea why? Is it because I never activate the personal website function?
