Translocation of elxis & ios res to other server

[e-isodos]

I have installed the elxis and ios res to a server (1and1) and now I want to move it a virtual server of the same company.

1. How I can do it, with out loosing any data?
2. Is there any problem with the activation code of IOS RES that I ' ve done to the previous server, (of course I am using the same domain)?

1. Get Backups (data & DB)
2. Change DNS
3. Upload Backups
4. Update Softdisk

If you are on the same domain the activation will be ok
